There was a modest increase in AP CSA exams from 2017 to 2019, but the number of AP CSP exams more than doubled. I expect that we will see an increase in the number of AP CSA exams as more students get interested in computing after taking AP CSP, however we need to prepare more AP CSP teachers to teach AP CSA.
Black students had the lowest pass rate of any racial group on both CSP and CSA. The pass rate for Black students was less than half of that for Asian students in 2019. This is true for many AP exams, not just CS.
While the number of women taking AP CS has increased, the percentage of women hasn’t made all that much progress. AP CSA is still the second worst AP exam in terms of the Log(Female/Male) and AP CSP is the fifth worst. The size of the circle is the number of exams. The majority of the exams have a higher percentage of females than males.
While AP CS has been growing, it still isn’t reaching as many students as other exams. English Language and Composition is 6x the size of CSP.
A better measure than the total number of exams per state is the number of exams per 100,000 of population (according to the 2010 census). The image below includes the top ten states.
There is quite a variance in the percentage of exam takers that are female in each state. With a high of 29.9% in Vermont and a low of 0% in South Dakota (0 females out of 3 exam takers) for AP CSA.
For AP CSP the high was Washington D. C. with 53.1% and the low was Kansas with 16.83%.
There is also quite a variance in the percentage of females who pass the exam. For AP CSA it ranged from 85.7 in Nebraska (18 out of 21 females passed the exam) to 0% (since no females took the exam in South Dakota). Montana, Wyoming, and North Dakota have 0% on the map because the college board won’t publish the results for a group if less than 5 people in that group took the exam. In Montana two females took the AP CSA exam, in Wyoming it was one, in North Dakota it was four. South Dakota had 0 females take the AP CSA exam in 2019.
For AP CSP it ranged from 100% in South Dakota (6 out of 6) to 38.5% for the District of Columbia.
Here is the percentage of AP CSA exam takers that were Black for 2019.

I have downloaded the data and written Python programs to process it along with data from prior years. See the following spreadsheets for more information.
The number of AP CSA exams taken in the U.S. increased from 60,040 in 2018 to 64,197 in 2019 (a 7% increase). The number of AP CSP exams taken in the U.S. increased from 70,864 in 2018 to 94,360 in 2019 (a 33% increase).
The percentage of females taking the AP CSA exam increased from 24% in 2018 to 24.5% in 2019. However, this is still the second worse percentage of females in AP after Physics C:elec. & magnet which is 24.3%. The percentage of females taking the AP CSP exam increased from 31.5% in 2018 to 32.7% in 2019. This is still the 5th worst percentage of females. Most (26 of 38 – 68%) of the AP exams have a higher percentage of females than males taking the exam.
The average pass rate on CSA for 2019 was 69.2% and for CSP it was 71.7%. These pass rates are better than Calculus AB which was 57.8%. However, the pass rate for Black students on CSA was 37.1% and CSP was 41.9%. The Hispanic pass rate was 46.9% for CSA and 54.4% for CSP. The Female pass rate for CSA was 66.8% and for CSP was 69.4%.
The top 10 states with the highest number of exams per 100,000 of population are:
Where are AP CSA and CSP courses offered? The interactive map below shows the locations of schools that passed the College Board Audit to offer AP CS courses in 2018-2019 in four states: California, Georgia, Michigan and Texas. Data for other states are under preparation.
This map is visualized by Willa Hua, a data visualization enthusiast. It is meant to supplement the data and report from Barbara Ericson, assistant professor in the School of Information at the University of Michigan who has been working with AP CS data since 2004.
In 2018, more women took Advanced Placement (AP) exams than men, as the comparative
pie charts below show. However, when it comes to AP Computer Science (CS) exams, more
specifically, AP Computer Science A (CSA) and AP Computer Science Principles (CSP), only
28% of all exam takers are female, and the percentage of female among those who passed
the exam is even lower.
2018 Gender Distribution of Exam Takers and Exam Passers
If we take a closer look at the statistics, we’d find that for the first time, AP CSA is not the most
male-skewed of all of the AP exams. Nonetheless, AP CSA is the 2nd most male-skewed as
shown in the 2017 v.s. 2018 comparison below. The further away from the center, the more
gender-skewed is the AP exam subject. AP CSP, which is a newer exam piloted in 2016 and
released in 2017, ranks the 5th most male-skewed exam. Both exams made significant
process towards a balanced pool of exam takers in 2018.
2018 Log base 2 of # females / # males
Percentage Female Exam Takers
In addition to the growth of the number of exam takers, both the CSA and CSP witnessed a
growth of the percentage of female exam takers. For CSA, as shown below, 23.9% of exam
takers were female: a 0.4% improvement from 2017.
Female Pass Rate
How many of these females passed compared to males? The female pass rate has been
steadily approaching the overall pass rate. In 2018, 65.0% of female exam takers passed the
AP CSA exam, versus the 67.4% pass rate of all exam takers, and 68.5% female passed the
CSP versus the 71.0% overall.
Overall and Female Pass Rate from 2006 to 2018
Percentage Female Exam Takers by State
CSA
The percentage of female exam takers varies from state to state. For AP CSA, the range was
from 0% (no female exam takers in Mississippi and South Dakota) to 37% (Alaska, not
pictured below).
The states with top five most percentage of female exam takers are Alaska (37%), Washington
(27%), New-York (27%), California (27%) and West Virginia (27%).
Percentage of female AP CSA exam takers by state
CSP
The percentage of female exam takers increased slightly for CSP from 30% in 2017 to 31% in
2018. On the state level, however, the percentage of female exam takers varies from 0% (no
female exam takers in Montana) to 40% (New York) and 47% (District of Columbia).

Racial Composition in the U.S. v.s. in AP and AP CS Exams
Racial representation in AP CS Exams*
Looking at AP CSA and CSP exams as an aggregate, the majority of AP CS exam takers are whites (45.8%) and Asians (27.1%). The graph above shows the racial decomposition of AP exam takers and exam passers in 2018, in comparison with the entire U.S. population. While young Hispanics constituted 22% of all AP exam takers, they were relatively underrepresented in AP CS exams. Blacks were underrepresented in both AP CS exams and AP exams in general. In terms of passing the exam, the pass rates of Asians and whites were consistently higher than that of Hispanics and blacks. Though 6% of all AP exam takers were Native Americans, less than 0.5% of all AP CS exam takers were Native American, and they constituted only a 0.1% of exam passers.
Exam Takers and Pass Rate by State
For all AP exams in 2018, the average pass rate was 58.4%. AP CSA had a pass rate of 67.4% and AP CSP 71.0%. Among the major racial groups, Asians had the highest pass rate and blacks the lowest, as shown in the table of pass rate below.

Zooming in on the Minorities
As mentioned before, Hispanics and blacks are two major race groups underrepresented in AP CS exams. The interactive map below shows the number of exam takers and the pass rate by state in AP CSA 2018 for four groups respectively: blacks, black females, Hispanics, and Hispanic females.
This analysis is visualized and written by Willa Hua, a data visualization enthusiast. It is meant to supplement the data and report from Barbara Ericson, assistant professor in the School of Information at the University of Michigan who has been working with AP CS data since 2004.
*Data for the racial composition for the U.S. population comes from Kaiser Family Foundation estimates based on the Census Bureau’s American Community Survey, 2008-2017. Persons of Hispanic origin may be of any race; all other racial/ethnic groups are non-Hispanic.
There was a huge increase in Advanced Placement (AP) Computer Science Principles (CSP) exam takers nationally (from 43,780 in 2017 to 70, 864 in 2018 – a 62% increase). The Computer Science A (CSA) exam also grew (from 56,088 in 2017 to 60,040 in 2018 – a 7% increase).
The number of exam takers for all states for AP CSA from 1998 to 2018 is at
AP CSA is no longer the most male skewed of any of the AP exams as of 2018. The most male skewed exam is now Physics C: Elec. & Magnet. However, AP CSA is the 2nd most male skewed of the AP exams and AP CSP is the 5th most male skewed after Physics 2 and Physics C: Mechanics. Thanks to Willa Hua from the University of Michigan for creating the following graph.
The percentage of female exam takers increased slightly for CSA from 23.5% in 2017 to 23.9% in 2018. However, the percentage of female exam takers varies from state to state. For AP CSA, the range was from 0% (no female exam takers) in Mississippi and South Dakota to 37% in Alaska (not pictured below). Five states had 27% female exam takers: West Virginia, California, Arkansas, New-York, and Washington. Thanks to Willa Hua from the University of Michigan for creating the following graph.

The female pass rate for the CSA exam in 2018 was the
highest ever at 65%, but this was still a bit lower than the pass rate for
males, at 68.2%. The female pass rate on
the CSP exam fell slightly from 70.4% in 2017 to 68.5% in 2018. The female pass rate at 68.5% in 2018 was
slightly lower than the male pass rate, at 72.1%. The female pass rate is lower than the male
pass rate on many AP exams, including Biology, Calculus AB, and US History. The
female pass rate is higher than the male pass rate for English Lit. & Comp.
and Studio Art – Drawing. Black and Hispanic females had a lower pass rate in
2018 on the AP CSA and AP CSP exam than Black and Hispanic males.

The Black female pass rate varies quite a bit. Arkansas had 21 Black female students take
the AP CSA exam and only one pass it, which is a pass rate of 4.76%. Connecticut
had 4 of 6 Black female students pass the AP CSA exam, which is a pass rate of
66.67%. In 16 states, no Black female student took the AP CSA exam (Alaska,
Hawaii, Idaho, Iowa, Kansas, Maine, Mississippi, Montana, Nebraska, New Mexico,
North Dakota, Oregon, South Dakota, Utah, Vermont, and Wyoming). Only 7 states had more than 10 Black female
students pass the AP CSA exam (California 13/36, Maryland 15/59, Virginia
16/54, New Jersey 19/48, Georgia 22/56, New York 26/77, and Texas 28/64).
Only 10 states had more than 10 Hispanic females pass the AP CSA
exam (Ohio 12/13, Georgia 13/29, Washington 15/23, Virginia 31/55, Illinois
33/60, New Jersey 34/72, New York 45/153, Florida 71/152, Texas 107/355, and
California 146/453).
All states had students take the AP CSA exam, but the number
of exams per 100,000 of population varied from 43 (New Jersey) to 0.2 (South
Dakota). All states had students take
the AP CSP exam, but the number of exams per 100,000 of population varied quite
a bit from 59 (Maryland) to 1 (Kansas and Montana).

Good company in a journey makes the way seem shorter. — Izaak Walton
I am an assistant professor in the School of Information at the University of Michigan. I have been woking in computing education research since 2004. I was at Georgia Tech as a research scientist from 2006 to 2018. I have run teacher professional development, created computing summer camps for 4th – 12+ graders, ran competitions, ran weekend workshops with youth serving organizations, and written books (both paper and ebooks). I have worked on two ebooks for Advanced Placement Computer Science: one for AP CSP at http://tinyurl.com/StudentCSP-newand one for AP CSA at http://tinyurl.com/JavaReview-new
I have been working on mixed-up code problems, which are also called Parsons problems. The correct code to solve a problem is provided, but the code is broken into blocks and mixed-up. The learner must select blocks and put them in the correct order.
