National Assessment of Educational Progress (NAEP); State achievement tests are standardized tests.These may be required in American public schools for the schools to receive federal funding, according to the US Public Law 107-110 originally passed as Elementary and Secondary Education Act of 1965, and currently authorized as Every Student Succeeds Act in 2015.
CAST tests are the state's science tests that are to be taken in fifth grade, eighth grade, and once in high school (tenth, eleventh, or twelfth grade). The CAAs for Science are the equivalent of the CASTs for "students with the most significant cognitive disabilities" who are therefore unable to take the CASTs.
Comparison of the various grading methods in a normal distribution, including: standard deviations, cumulative percentages, percentile equivalents, z-scores, T-scores. In statistics, the standard score is the number of standard deviations by which the value of a raw score (i.e., an observed value or data point) is above or below the mean value of what is being observed or measured.
The top grade, A, is given here for performance that exceeds the mean by more than 1.5 standard deviations, a B for performance between 0.5 and 1.5 standard deviations above the mean, and so on. [17] Regardless of the absolute performance of the students, the best score in the group receives a top grade and the worst score receives a failing grade.

The following standardized tests are designed and/or administered by state education agencies and/or local school districts in order to measure academic achievement across multiple grade levels in elementary, middle and senior high school, as well as for high school graduation examinations to measure proficiency for high school graduation.
A large standard deviation indicates that the data points can spread far from the mean and a small standard deviation indicates that they are clustered closely around the mean. For example, each of the three populations {0, 0, 14, 14}, {0, 6, 8, 14} and {6, 6, 8, 8} has a mean of 7. Their standard deviations are 7, 5, and 1, respectively.
The average student takes about 10 of these tests per year (e.g., one or two reading comprehension tests, one or two math tests, a writing test, a science test, etc.). [59] The average amount of testing takes about 2.3% of total class time (equal to about four school days per year).
