STUDENT GRADE DISTRIBUTIONS

Introduction

The May 2007 College Board AP Exams were taken by 1,464,254 students from 16,464 secondary schools.  College and high school teachers, called readers, who are familiar with college-level course demands, scored the free-response sections from the 2,533,431 examinations taken.  Computers at ETS® scored the multiple-choice sections. 

The Chief Readers, relying on their subject-matter expertise, statistical equating data, data from comparability studies, and historical trends, determine the grade-setting thresholds for the 5-point AP grade scale: 5 = extremely well qualified, 4 = well qualified, 3 = qualified, 2 = possibly qualified, 1 = no recommendation.  Listed below are the Chief Readers who directed the scoring of the free-response sections of the May 2007 exams.

Summary Table of Students’ Grades 

The grades earned on the May 2007 AP Examinations are summarized in the form of grade distributions shown in the table on the next two pages.  For each exam, the table provides the number and percentages of students receiving each grade, the total number of students, and the mean and standard deviation of grades.  It should be noted that AP students are among the most academically able students of the college-bound group and that AP grading standards are held to higher standards in their secondary school AP course work than college students are in comparable courses at most colleges.
