Test Results Definitions
Number Enrolled—A count of students in the selected entity (i.e., state, county, district, school, or student group) who are
eligible to take the CAAs for English language arts/literacy (ELA) and mathematics in grades 3–8, and grade 11.
Number Tested—A count of students in the selected entity (i.e., state, county, district, school, or student group) who were
administered the CAAs in ELA and mathematics. This number excludes students not tested by parent/guardian
request, students not tested due to a significant medical emergency, and students who were assigned to take the test,
but did not test.
Number of Tests with Valid Scores—A count of students tested in the selected entity
(i.e., state, county, district, school, or student group) and responded to enough questions on the test
to generate a valid score. Scores that are invalidated are not included in this aggregation.
Mean Scale Score—The sum of scale scores for students with valid scores in the selected entity (i.e., state, county,
district, school, or student group) divided by the Number of Tests with Valid Scores.
For more information, please visit the Scale Score Ranges page.
Note: The percent of students in the selected entity (i.e., state, county, district, school, or student group) at a particular
performance level is the sum of the number of students at a particular performance level divided by the total number of
students across all performance levels for that entity.
