Reliability and validity estimates of the Brigance K&1; screen based on a sample of disadvantaged preschoolers

The reliability and validity properties of the Brigance K&1; screen were examined with a sample of 134 Head Start children preparing to enter kindergarten. Reliability estimations indicated high interrater agreement and high overall internal consistency and test–retest reliabilities. Construct validation procedures included examination of the Screen's correlations with the cognitive processing and achievement subscales of the K‐ABC. Prediction/outcome analyses, intended to explore the test's accuracy in predicting special education status at the end of preschool, indicated a relatively high false negative rate and a moderate true positive rate. © 1999 John Wiley & Sons, Inc.     

Comparison of the K-ABC and PPVT-R with Head Start Chidren

The relationship between the new Kaufman Assessment Battery for Children (K-ABC) and the Revised Peabody Picture Vocabulary Test (PPVT-R) Forms L and M was explored for a sample of 30 predominantly black Head Start children. The highest correlations occurred between the K-ABC Achievement Scale and the PPVT-R. The K-ABC Expressive Vocabulary subtest correlated moderately highly with PPVT-R Form L, while the K-ABC Riddles subtest correlated moderately highly with PPVT-R Form M. Mean standard scores for the K-ABC Scales and subtests ranged from 11 to 20 points higher than those obtained on the PPVT-R. It would not appear redundant to administer the PPVT-R in addition to the K-ABC when one needs a receptive vocabulary measure.     

The relationship between young children's academic achievement and measures of intelligence

To test the construct validity of brief measures of intelligence and explore how well these instruments relate to academic performance, the WPPSI-R, the Kaufman Brief Intelligence Scale (K-BIT), Draw-A-Person: Quantitative Scoring System (DAP:QSS), and the K-ABC Achievement Scale were administered to 50 kindergarten and first-grade children. Results indicated that all measures provide similar scores, all in the average range. All brief measures related significantly to academic achievement. Implications of the findings are discussed, and a battery for screening young children is offered.     

Relationships between age and raw score increases on the Kaufman-assessment battery for children

Raw scores on the 16 K-ABC subtests and the total raw scores on the sequential and simultaneous processing scales and the achievement scale were correlated with age in months for two separate samples, each subdivided by race and sex: the K-ABC standardization sample (N = 2000) and an additional group of blacks and whites tested during the development of the K-ABC sociocultural norms (N = 615). Within each sample, the highest and lowest correlations from all race/sex groups were contrasted across all K-ABC subtests and scales. All correlations between age and raw scores were statistically significant (p ⩽ .05). No significant differences occurred in the magnitude of these relationships as a function of race/sex grouping, supporting the construct validity of the K-ABC as a developmental measure of children's aptitude and achievement for blacks, whites, Hispanics, males, and females.     

Head start children''s conceptions of and expectations for their future schooling

This study examined children's conceptions of and expectations for their future schooling, determined whether participation in a Transition Demonstration could affect these, and explored how these are related to children's academic achievement. Two cohorts, 151 former Head Start children completing kindergarten, and 171 children completing Head Start, were assessed. Two major themes in children's conceptions of school emerged: play and the cognitive or learning environment. Children realistically talked about the work of school becoming less play centered, more difficult, and more centered on academics as they moved from grade to grade. Children in the Demonstration group in both cohorts gave significantly more responses to the questions than those in the Comparison. Children's expectations for their future schooling were optimistic. There were several small but significant correlations between children's conceptions and expectations for school and their academic achievement as measured by subtests of the Wood-cock-Johnson-R.     

Validity of the K-ABC for a black preschool population

The validity of the Kaufman Assessment Battery for Children (K-ABC) was investigated with a sample of Black low SES preschool children. The sample consisted of 38 Black children who were enrolled in a Head Start program. The Stanford-Binet Intelligence Scale (SB-LM) was used as a criterion against which to compare K-ABC scores. While some support was obtained for the convergent and construct validity of the K-ABC, the results of this study suggest it may be no more culture fair for Black preschool children than is the SB-LM.     

An investigation of the K-ABC,WISC-R,and W-JPB,part two,with learning disabled children

The purpose of this study was to examine the relationship of the Kaufman Assessment Battery for Children (K-ABC), the WISC-R, and the Woodcock-Johnson Psychoeducational Battery (W-JPB), Part Two, with children who experience learning disabilities. Correlational analyses were used to examine relationships among the WISC-R, K-ABC Mental Processing and Achievement scales, and the W-JPB Achievement scales. Thirty-four children with learning disabilities (mean age 8–11 years) received all three measures. Correlation coefficients indicated stronger and more consistent relationships between the WISC-R and W-JPB Achievement tests than between the K-ABC and W-JPB Achievement tests. Significant relationships between the WISC-R Full Scale IQ and the K-ABC Mental Processing Composite (MPC) revealed evidence of validity for this learning disabled sample. However, correlation coefficients among the K-ABC Achievement subtests and the W-JPB Achievement clusters indicated both convergent and discriminant validity. Thus, it is suggested that both the K-ABC MPC, for assessment of cognitive abilities, and the W-JPB Achievement clusters could be employed in discrepancy formulas for special education placement of children with learning disabilities.     

Kindergarten screening results as predictors of academic achievement,potential, and placement in second grade

The ability of a battery of kindergarten screening measures to predict educationally relevant criteria was investigated. Subtest scores on The Vane Test of Language and The Vane Kindergarten Test administered at the beginning of kindergarten were examined and compared to the Metropolitan Achievement Test scores in reading and math, The Otis-Lennon School Ability Test index, and placement into special education or high achievement programs at the end of second grade. A weighted combination of subtests accurately predicted 77% of the children classified as special education students. The same battery also predicted 73% of the children who were classified as high-achieving students.     

Head Start Parents' Beliefs about Their Children's Abilities, Task Values, and Performances on Different Activities

As part of larger intervention study designed to facilitate the transition of Head Start children into kindergarten and the early elementary grades, we assessed parents beliefs about former Head start children's abilities and values in several activity domains—academics, sports, and social skills—during the children's kindergarten ten year. Parents' expectations for their children's future also were examined. One hundred and twenty-four parents and 155 children participated; all children had attended Head Start, and the sample is ethnically and racially diverse. One group of children and parents received the additional services, and a second group did not. Parents, were quit optimistic about their children's prospects for the future. There were ethnic differences in parents were quit optimistic about their children's prospects for the future. There were ethnic differences in parents' beliefs about children's abilities and future prospects in different areas. Parents beliefs related both to children's attitudes toward school and to their performance on mathematical and reading achievement tests.     

Coordination between Head Start and Elementary Schools to Enhance Children’s Kindergarten Success

ABSTRACT

Research Findings: This study examines efforts by Head Start programs to coordinate with elementary schools and seeks to better understand how coordination practices may support children’s transition to and success in kindergarten. Data were drawn from a nationally representative sample of Head Start children (N = 2,019) followed through kindergarten. Findings suggest that Head Start programs are engaging in a variety of activities to coordinate with elementary schools around the transition to kindergarten. Results of lagged OLS regression analyzes found that coordination efforts were significantly related to children’s language and mathematics skills in kindergarten for children attending elementary schools engaging in limited school transition practices to support school entry, suggesting that coordination practices initiated by preschools may play a compensatory role for children. In addition, results suggest that direct meetings between Head Start and kindergarten teachers are predictive of higher language skills in kindergarten. Policy or Practice: Efforts by Head Start programs to coordinate with elementary schools may be particularly important for children’s academic skills when their elementary schools are less engaged in transition practices. In addition, meeting in person and having a key person responsible for the kindergarten transition may be key ingredients to coordination that yields better outcomes for children.     

Normative achievement assessment of gifted children: Comparing the K-ABC,WRAT, and CAT

The Kaufman Assessment Battery for Children (K-ABC) purports to assess fluid and crystallized intelligence via processing and achievement subtests, respectively. Eight K-ABC Mental Processing and five K-ABC Achievement subtests were administered to 41 gifted students. Scores were subsequently compared to concurrent achievement measures from the California Achievement Test (CAT), as well as previously obtained mental ability measures (Wechsler Intelligence Scale for Children-Revised [WISC-R], Stanford-Binet [SB], and Wide Range Achievement Test [WRAT] achievement scores). In general, K-ABC mental ability scores were lower than WISC-R and SB IQs. K-ABC achievement scores were consistent with K-ABC mental ability scores, but more highly related to SB and WISC-R VIQ (r = .42 and .40, respectively) than to WISC-R FSIQ (r = .16) and PIQ (r = .09), or to the K-ABC Mental Processing (Composite r = .17), Simultaneous Processing (r = .08), and Sequential Processing scores (r = .20). With the exception of WRAT Word Recognition, WRAT, K-ABC, and CAT achievement scores were similar. The patterns of intercorrelations suggest that the K-ABC achievement scores are more verbally loaded than are the CAT and WRAT achievement measures.     

Convergent and discriminant validity of the mental processing scales of the Kaufman Assessment Battery for Children

Convergent and discriminant validity of the Mental Processing Scales of the Kaufman Assessment Battery for Children (K-ABC) were examined using 51 first-grade children. Convergent validity was assessed using the Reading Recognition and Comprehension subtests of the Peabody Individual Achievement Test. Discriminant validity was assessed using a measure of anxiety/self-esteem, the Child Anxiety Scale, and a measure of hyperactive behavior, the Hyperactivity scale of the Achenbach Child Behavior Checklist. Results supported the convergent validity of the K-ABC; correlations with reading achievement were fairly large. The discriminant validity received only partial support. The K-ABC did not correlate with the Child Anxiety Scale, but did show rather large correlations with the measure of hyperactive behavior. Implications for understanding what the K-ABC Mental Processing Scales are measuring are discussed.     

Assessing Noncognitive Aspects of School Readiness: The Predictive Validity of Brief Teacher Rating Scales of Social–Emotional Competence and Approaches to Learning

Research Findings: Head Start teachers completed brief rating scales measuring the social–emotional competence and approaches to learning of preschool children (total N = 164; 14% Hispanic American, 30% African American, 56% Caucasian; 56% girls). Head Start lead and assistant teacher ratings on both scales demonstrated strong internal consistency and moderate interrater reliability. When examined longitudinally, preschool teacher–rated approaches to learning made unique contributions to the prediction of kindergarten and 1st-grade academic outcomes, need for supplemental services, and grade retention, even after we accounted for preschool academic skills. In contrast, preschool teacher–rated social–emotional competence made unique contributions to the prediction of reduced behavior problems and peer difficulties in kindergarten and 1st grade. Practice or Policy: The findings demonstrate that preschool teachers are able to provide distinct and reliable ratings of child social–emotional competence and approaches to learning using brief rating scales, with validity for predicting elementary school adjustment.     

Predicting school performance with the early screening inventory

Criteria are proposed for defining and selecting preschool developmental screening instruments. These criteria include the purpose, breadth, and psychometric properties of screening tests. The Early Screening Inventory (ESI) is a developmental screening instrument designed to satisfy these criteria. The test samples developmental, rather than school achievement, abilities and focuses on performance in a wide range of developmental areas. The results of several reliability and validity studies performed on the ESI are presented, demonstrating that the ESI predicts school performance with moderate to excellent accuracy through the end of second grade. The usefulness and limitations of the ESI in predicting school performance from kindergarten to grade four are discussed.     

School Absenteeism through the Transition to Kindergarten

ABSTRACT

Using nationally representative data from the Family and Child Experiences Survey 2009 Cohort (n = 2,798), this study examined patterns of absenteeism and their consequences through the transition to kindergarten. Overall, children were less likely to be absent in kindergarten than from Head Start at ages 3 and 4. Absenteeism was fairly stable across these early years, but children who experienced two years of Head Start were less likely to be absent in kindergarten than their classmates who only attended the program for one year. Ultimately, absenteeism at both ages 3 and 4 was associated with lower math and literacy achievement. However, children who experienced two years of Head Start and were more frequently absent demonstrated greater language development through the end of kindergarten as compared with children who only attended the program for one year. Policy implications are discussed in light of the complexity of early childhood education attendance in the United States.     

Understanding Gender Differences in Thinking Styles of Gifted Children

The accuracy of the Brigance K&1 screen in the early detection of Head Start children with possible cognitive/academic giftedness, was explored in this study. Data were collected from a sample of 134 children, 13 of whom were identified as potentially gifted on the basis of performance on the K‐ABC. Potentially gifted children performed significantly better on the Brigance than nongifted children. Group differences were large and exceeded one standard deviation on the K&1 total score. Classification analyses indicated that use of the technical manual criteria underreferred potentially gifted children. However, use of local criteria established that the K&1 screen has good sensitivity (>80%) and acceptable specificity (>70%) in relation to concurrent and predictive cognitive/academic outcomes. Teacher ratings were ineffective in detecting potentially gifted children. The K&1 screen may be helpful in the early detection of low‐income children who may be cognitively/academically gifted.     

Playing with others: Head Start children's peer play and relations with kindergarten school competence

Time-sampled observations of Head Start preschoolers’ (N = 264; 51.5% boys; 76% Mexican American; M = 53.11 and SD = 6.15 months of age) peer play in the classroom were gathered during fall and spring semesters. One year later, kindergarten teachers rated these children's school competence. Latent growth models indicated that, on average, children's peer play was moderately frequent and increased over time during preschool. Children with higher initial levels or with higher slopes of peer play in Head Start had higher levels of kindergarten school competence. Results suggest that Head Start children's engagement with peers may foster development of skills that help their transition into formal schooling. These findings highlight the importance of peer play, and suggest that peer play in Head Start classrooms contributes to children's adaptation to the demands of formal schooling.     

Characterizing disability in Head Start programs: Not so clearcut

Head Start programs are required to set aside at least 10% of program slots for children with disabilities, but the percentage of children with disabilities served varies depending on the criteria used and source of the information. This study used the Head Start Family and Child Experiences Survey (FACES) 2000 data for a nationally representative sample to identify subgroups of children meeting three different criteria for having a disability or developmental delay. Results indicated that about one-third of children in Head Start (33%) met one or more of the criteria for a disability or delay, about one-third of those children (33%) met criteria for two or for all three of the subgroups. However, only 8% of children in Head Start had an Individualized Education Program (IEP). Children with disabilities or delays, regardless of the subgroup criteria used, had higher levels of many other risk factors associated with poor developmental and school readiness outcomes. They also exhibited poorer performance on early literacy, social, and behavioral measures both at entry into Head Start and at the end of kindergarten compared with children not in each of those subgroups. Implications of the findings for screening and assessment, serving children in Head Start programs, and the need for linkages between Head Start programs and the preschool special education system are discussed.     

Head Start Children: School Mobility and Achievement in the Early Grades

Abstract

The relationship of 2 school mobility indices (school changes and parental perceptions of mobility effects) to 2nd-grade academic achievement was examined. The sample comprised 90 children who had attended Head Start and had made the transition to public school. Data also were obtained from the children's mothers. School mobility was defined as the number of school transfers over 3 years (kindergarten to Grade 2). Hierarchical regression analyses indicated that frequent school changes in the primary grades were related to lower achievement levels even after controlling for the child's sex and the effects of achievement prior to the school moves.     

Home language as a predictor of first-grade achievement for Anglo- and Mexican-American children

The utility of kindergarten screening measures in predicting first grade achievement was examined for 246 children classified as Anglo-American-English as home language (AA-E), Mexican-American-English as home language (MA-E), and Mexican-American-Spanish as home language (MA-S). All children were administered the Boehm Test of Basic Concepts, Draw-A-Design and Draw-A-Child subtests of the McCarthy Scales of Children's Abilities, and a Criterion Referenced Test at the beginning of kindergarten and at the end of kindergarten. The SRA Achievement Series was then administered during first grade. Stepwise multiple regression analyses were conducted for each group of children employing each set of kindergarten measures as predictors. All resulting equations were significant (p < .001) and revealed differential predictive power of the kindergarten measures as a function of ethnicity and home language, content of the criterion measures, and time of assessment. The Criterion Referenced Test was found to be a significant predictor of first-grade reading scores and the Draw-A-Design subtest emerged as a significant predictor of first-grade math achievement for the MA-S children, whereas the Boehm consistently emerged as a significant predictor and accounted for substantially more variance in first-grade reading and math scores for the AA-E and MA-E children. For all three groups, beginning kindergarten measures accounted for more variance in first-grade achievement than end of kindergarten measures. The importance of utilizing language measures, as well as predictive validity techniques, was discussed in relation to future cross-cultural research.
