Dig Deeper into AP Computer Science

The AP Computer Science exams are widely accepted by the computer science education community as one of the most reliable measures of high school computer science course-taking patterns. The College Board’s rigorous methodology and data gathering has enabled us to see trends in AP Computer Science A exam-taking over time, by state, by gender, and by ethnic group; as well as the impact of AP Computer Science Principles course, which launched in the 2016-17 school year. This page contains a summary of that data.

This data comes directly from the public spreadsheets available on a per-state basis from the College Board.

AP Computer Science Over Time

Change in ethnic group categories: In 2016, the College Board changed the ethnic group categories that they report. Prior to 2016, we considered the following to be underrepresented minority groups: American Indian, Black, Mexican American, Puerto Rican, and Other Hispanic. After 2016, we considered the following categories: American Indian/Alaska Native, Black, Hispanic/Latino, and Native Hawaiian/Other Pacific Islander.

2018 Outcomes

General

The total number of exams taken in CS increased as compared to 2017:

• CS A: +3,952 exams, or +7%
• CS P: +27,084 exams, or +62%
• All CS Exams: +31,036 exams, or +31%

Female student participation in CS increased as compared to 2017:

• CS A: +1,222 exams, or +9%
• CS P: +9,148 exams, or +69%
• All CS Exams: +10,370 exams, or +39%

Underrepresented minority student participation in CS increased as compared to 2017:

• CS A: +569 exams, or +7%
• CS P: +7814 exams, or +68%
• All CS Exams: +8,383 exams, or +42%

CS passing rates (score 3+) were lower for female and underrepresented minority students in 2018.

• All CS Exams: female student passing rate was 67% (-3% as compared to male students).
• All CS Exams: underrepresented minority student passing rate was 48% (-28% as compared to the students in the majority).

Female student participation

Female students comprised a low percent of AP CS exams:

• CS A: 24% of exams were taken by female students. This is an increase of 2% from 2017.
  
• CS P: 32% of exams were taken by female students. This is an increase of 2% from 2017.
• All CS Exams: 28% of all CS exams were taken by female students. This is an increase of 2% from 2017.

Female student passing rate was lower than male students:

• CS A: female student passing rate was 65% of exams (lower than male students by -3% passing rate and a mean score difference of -0.12).
• CS P: female student passing rate was 68% of exams (lower than male students by -4% passing rate and a mean score difference of -0.09).
• All CS Exams: female student passing rate of exams was 67% (lower than male students by -3% passing rate).

Underrepresented minority student participation

For 2018 College Board data, we consider the following ethnic group categories to be underrepresented minorities: American Indian/Alaska Native, Black, Hispanic/Latino, and Native Hawaiian/Other Pacific Islander. (Other categories reported by the College Board are Asian, White, Two or more races, Other, and No response.) Note that until 2016, the College Board reported demographics using different categories; for those years, the following ethnic group categories are considered to be underrepresented minorities: American Indian, Black, Mexican American, Puerto Rican, and Other Hispanic. (Other ethnic categories reported by the College Board include Asian, White, Other, and Not stated.) The majority is defined as White and Asian students.

Underrepresented minority students comprised a low percent of AP CS exams:

• CS A: 16% of exams were taken by underrepresented minority students. This is the same percent as 2017.
• CS P: 27% of exams were taken by underrepresented minority students. This is an increase of 1% from 2017.
• All CS Exams: 22% of all CS exams were taken by underrepresented minority students. This is an increase of 2% from 2017.

Underrepresented minority student passing rate was lower than the students in the majority:

• CS A: underrepresented minority student passing rate was 44% of exams (lower than the students in the majority by -28% and the same as 2017).
• CS P: underrepresented minority student passing rate was 50% of exams (-3% less than the percent passing in 2017, and lower than the students in the majority by -29%).
• All CS Exams: underrepresented minority student passing rate of exams was 48% (-28% as compared to the students in the majority).
