Students in 19 different schools were asked to answer a number of questions in order to evaluate the comprehensibility of the booklet entitled Your College Board Scores: Preliminary Scholastic Aptitude Test. Five hundred and sixty-five students, selected at random within these schools, completed the questionnaire. Information is provided on students' comprehension of the booklet, including their ability to convert test scores to percentiles and to predict SAT scores from a knowledge of PSAT scores. The perceived implication, by students, of the use of the PSAT for college admissions and for the prediction of college success is discussed. The booklet, in general, was comprehensible to the majority of students. However, some of the facts and concepts presented (e.g., prediction of SAT scores, use of interpolation, interpretation of a percentile) did prove difficult for many of the students. Comprehension was found to be positively related to scholastic aptitude.
