A Converting and Composing Procedure of the Scores for the "3 X" Scheme of Entrance Examination for Higher Education in China

When all candidates sit for all subjects of a large-scale examination, adding standardized scores from all subjects is a routinely recommended procedure to produce an overall rank of the examinees. However, under the "3 X scheme, this procedure causes problems and use of raw scores instead of standardized scores is often called for in this situation. With a simple example, this paper demonstrates that summing raw scores of different subjects of the higher education admission examinations is also problematic. An alternative procedure is proposed for converting the scores from different subjects including "X subjects and producing the "total scores" under the "3 X scheme. Criteria for scores/cases exclusion are also recommended.
