Assessment of Mathematical Concepts of Five-Year-Old Children

An instrument, the Schwartz Early Mathematics Inventory (SEMI), was devised to assess, by means of group administration, the mathematical achievement of children ages 3 through 5. The data presented concern only the first stages of the process and deal only with 215 kindergartners. A reliability of . 94 was obtained on the eighty-one items administered on 64 pages. The mean for items correct 43. 2. The proportion of correct responses for various items ranged from . 85 to . 12. The children had satisfactorily acquired the physical and emotional attributes necessary for completing the inventory, namely, holding a pencil or crayon, turning pages, recording responses in designated areas, and maintaining satisfactory attention for the 12 to 28 minutes required for administering each of the three portions of the SEMI.
