While more American public school students are taking Advanced Placement tests, the proportion of tests receiving what is deemed a passing score has dipped, and the mean score is down for the fourth year in a row, an 91制片厂视频 Week analysis of newly released data from the College Board shows.
Data released here this week by the New York City-based nonprofit organization that owns the AP brand shows that a greater-than-ever proportion of students overall鈥攎ore than 15 percent of the public high school class of 2007鈥攕cored at least one 3 on an AP test. The tests are graded on a scale of 1 to 5, the highest score.
Yet, as the number of AP exams taken in U.S. public schools has ballooned by almost 25 percent over the four years that the College Board has released its the percentage of exams that received at least a 3鈥攖he minimum score that the College Board considers predictive of success in college鈥攈as slipped from about 60 percent to 57 percent.
The mean score on the nearly 2 million AP exams taken by students in last year鈥檚 U.S. public graduating class was 2.83, down from 2.9 in 2004.
鈥淭hat happens,鈥� said Jennifer Topiel, a spokeswoman for the College Board. 鈥淎ny psychometrician can tell you that as participation grows, scores go down.鈥�
Still, Ms. Topiel said the score declines are a major concern for the organization, as are widening score gaps between some racial and ethnic groups, 鈥減articularly those among underrepresented students who are not being prepared and not having the same resources.鈥�
While the College Board sees the increasing number of test-takers as a positive phenomenon, she added, 鈥渨e feel very strongly that students should not be placed into AP classes without better preparation.鈥�
More Ones, Twos
Referring to scores on AP exams, Trevor Packer, the College Board vice president who oversees the AP program, said: 鈥淲e鈥檙e seeing more twos than ever before. We鈥檙e seeing more ones than ever before.鈥�
Asked whether at some point the College Board would determine that broadened access to the program wasn鈥檛 worth the deteriorating scores, Mr. Packer said, 鈥淚f I were to see two years of statistically significant declines [in any given subject], I鈥檇 start to get nervous.鈥�
The percentage of Advanced Placement exams taken at U.S. public schools in all subjects that registered scores of 3, 4, or 5 out of 5 has dipped over the past four years, both for the nation as a whole and for all racial and ethnic categories, except among Asian-Americans.

But right now, he said, 鈥渨e do not have any evidence that we need to increase restrictions on schools鈥� that want to offer AP courses.
Daria L. Hall, the assistant director for K-12 policy development for the Washington-based 91制片厂视频 Trust, a nonprofit group that promotes high academic standards for disadvantaged students, said high scores and wide access need not be mutually exclusive.
鈥淭hese findings shouldn鈥檛 be misinterpreted as an unavoidable trade-off between greater and more equitable access to high-level courses and raising achievement鈥攖hat by letting more students into them, we inevitably lower their quality,鈥� Ms. Hall wrote in an e-mail.
鈥淭o change these patterns,鈥� she wrote, 鈥渨e need to get serious about ensuring that college-prep coursework really provides students with what they need to be successful. Just slapping a new title on the same old courses won鈥檛 boost achievement鈥攊t鈥檒l only give students a false sense of promise that they will be college-ready.鈥�
The mean grade earned on AP exams taken at U.S. public schools has declined in the past four years for students in all racial and ethnic categories, except for those in the Asian category.

Terry B. Grier, the superintendent of the 71,000-student Guilford County school district in Greensboro, N.C., and a panelist invited here by the College Board to talk about the benefits of AP exams, said that while he wants all his students to score as high as possible, he鈥檚 willing to live with a dip in AP scores overall if it means more students are taking the exams.
鈥淚鈥檇 rather a student take an AP test and score a 2 than take a quote 鈥榟onors course鈥� and get an A in it,鈥� Mr. Grier said at the Feb. 13 release of the AP report. 鈥淭hat student is going to be better prepared at the college level.鈥�
鈥淓ven if they don鈥檛 score [well on the AP exam], they will be more successful in college than those who haven鈥檛 taken the AP exam at all,鈥� echoed Jean C. Robinson, a professor of political science at Indiana University Bloomington whom the College Board also invited to speak.
Although local anecdotal evidence may support that contention, Mr. Packer said, 鈥渢here鈥檚 no research to support that.鈥�
Gaps in Scores
The percentage of Advanced Placement exams in all subjects that received a score of at least 3 has dipped over the past four years, the 91制片厂视频 Week analysis shows, both for the nation overall and for most racial and ethnic categories. Asians, Asian-Americans, or Pacific Islanders are the exception.
At the same time, the mean grade earned on AP exams has declined for students in all racial and ethnic categories, except for those in the 鈥淎sian, Asian-American, or Pacific Islander鈥� category.
In releasing the report, College Board officials emphasized the rise in the number of students who graduate from high school having scored a 3 or higher on at least one AP exam. The program offers exams in 37 subject areas; students who pass them can qualify for college credit.
The College Board reported that more than 15 percent of the entire public high school class of 2007 had earned at least one AP exam grade of 3 or higher, compared with fewer than 12 percent in 2002, a change that organization characterized as 鈥渟ignificant and consistent improvement.鈥�
Still, marked and widening score gaps exist between different racial and ethnic groups, especially those that have been historically underrepresented in pools of AP exam-takers.
The group classified by the College Board as Asian, Asian-American, or Pacific Islander, which has consistently participated in AP exams at a disproportionately high rate relative to that group鈥檚 percentage of overall graduating classes, was the only group to post a mean-score improvement.
Scores in that category inched up from 3.04 to 3.05 over the past four years, the 91制片厂视频 Week analysis shows. That group also slightly increased its percentage of passing AP scores over the four-year span, with the proportion of tests that received at least a 3 edging up from 63.3 percent in 2004 to 63.4 percent in 2007.
By contrast, the percentage of passing exams taken by Hispanic students slipped by 5.5 percentage points over the past four years, to 43 percent in 2007. The percentages of passing scores among the group the College Board refers to as black or African-American slipped by nearly 4 points, to just 25 percent.
The mean scores of exams taken by both black and Hispanic students, two groups that have traditionally been underrepresented in AP courses, also dropped marginally from their 2004 levels.
The numbers for Hispanic students would be even lower, Mr. Packer of the College Board said, were it not for the Spanish-language exam.
鈥淭he AP Spanish-language exam presents an entr茅e to the AP program鈥� for many Hispanic students, he noted. Without that class, he said, 鈥渢he percentage of Hispanic students sitting in an AP class and earning a score of 3 or better drops to 7.5 percent.鈥�
鈥楲ack of Equity鈥�
Among white students, by far the largest single group, the percentage of exams earning at least a 3 dipped from 63.6 percent in 2004 to 62 percent in 2007. The gap in the passing-grade percentage between black and white students in the past four years widened from roughly 34 percentage points to nearly 37 points.
鈥淲hile more African-Americans, Hispanics, and Native Americans are taking AP exams in greater numbers,鈥� said Mr. Packer, there remains 鈥渁 true and startling lack of equity.鈥�
The College Board also released some information about the results from its recent nationwide audit of AP courses that it had declined to make available in November: Of the 146,671 course syllabuses submitted by teachers of AP classes, 93 percent were eventually approved.
However, more than 2,000 of the 16,464 secondary schools worldwide that offered at least one AP course during the 2006-07 school year are no longer offering the program this year. (鈥淣umber of Schools Offering AP Falls After First Audit of Courses,鈥� Nov. 14, 2007.)
The audit was launched amid concerns about whether the program鈥檚 rapid growth had diluted its quality.
