This study describes the characteristics of students who made perfect
scores on one or more subtests (English, Mathematics, Reading, Science
Reasoning) of the PLAN. The sample were 4,751 perfect scorers from a
total population of 374,527 students (mostly sophomores) who took the
test in the fall of 1991. Boys had a higher incidence of perfect score
s than girls in Mathematics while more girls than boys had perfect sco
res in English. There were no significant differences between boys and
girls on Reading and Science Reasoning. Comparisons are presented on
perfect scorers by gender, ethnicity, and subtest performance. Finally
, a profile is provided on the career choices of perfect scorers.
