CITO score

The CITO-test is a standardized test for educational achievement that is administered in the final grade (when children are 11 or 12 years old) of elementary school. The CITO-test consists of multiple choice items in 4 different educational skills, namely Arithmetic, Language, Study Skills, and Science and Social Studies. All scores on the scales are standardized to percentile scores to correct for differences in the number of items across the years. The first 3 test scales are combined to a standardized Total score (also called CITO final test score), which is standardized on scale from 500 to 550.

The information on CITO-score is obtained at different ways. Initially, we obtained the CITO final test scores and sub scores from surveys mailed to teachers of twins. Because results are only available near the very end of the school year and the response was low, we later requested the parents to report the scores on the CITO final test scores and sub scores. For a small number of twins, the CITO-scores are obtained by linking our data to the national base of CITO, by using the LVS data, and by project (YS_DT). In addition to the form with extended information on CITO scores, the CITO final test scores is also asked in a mailed survey to parents of 12 year old twins and in the mailed self report surveys (DHBQ). Combined over the different ways in which the data was collected, information on Cito final test scores is is available for about 17000 twins/siblings, and for about 12000 twins information on subtest is available.
