The TAKS or Texas Assessment of Knowledge and Skills is a series of exams given throughout the K-12 education of public school children in the state of Texas. Students take TAKS in all their core subject areas (Social Studies, Reading or English Language Arts, Math, and Science) and are required to take exit TAKS exams in their 11th-grade year, which they must pass in order to graduate. TAKS, like many standardized tests, has it's own grading system, which is scaled to a perfect score of approximately 2800. It is difficult for students, parents, and even sometimes educators to translate that into something that is easily understood. What's more, the TAKS score a student receives is not consistent from year to year based on the number of questions they got right because it is scaled to the number of students taking each exam and their individual performances. It is valuable to have a percentage score to use for understanding TAKS scores, giving grades on benchmarks, and planning for success.

1
Find the TAKS score frequency distribution for the exam in question. Ask the testing coordinator at your school for this information. You will not be able to convert the score to a percentage grade without it.

2
Follow the formula for conversion and plug in the appropriate numbers from your frequency distribution document.
The formula is: PR(x) = (( f / 2 + L ) / N )100
x = scale score in question
f = frequency of the scale score in question
L = cumulative frequency associated with the next lowest scale score
N = number of examinees

Work the formula, first dividing your f by 2 and then adding your L. Divide the sum by N and multiply the result by 100. For example, if x is 2400, f is 2494, L is 187323 and N is 198622, then x is 94.9391. Round up to 95.
