FAQ: How do I record out-of-range CASAS & TABE scores?

At times, student test results will be at the very top or bottom of a CASAS or TABE score range. These extreme scores are considered to be inaccurate.

CASAS out-of-range score charts can be found in the CASAS manual. If you don't have a manual, ask your local CASAS tester for a copy.

TABE out-of-range score charts for the full/complete battery and survey are Excel files. You can find them here: MN ABE Assessment - TABE. Under Score Validity Charts, look for “Complete Battery Validity Chart” and “Survey Validity Chart.”

Scores BELOW the accuracy range

For pre- and post-tests:

DO NOT record the test and scores. Retest immediately using a lower test form; record the results in the data system.

If students score below the range on the lowest form (CASAS 27A or 28A), enter the lowest possible accurate score into the data system - e.g. 153 for form 27/28.

Scores ABOVE the accuracy range 

For pre-tests:

DO NOT record the test and scores. Retest immediately using the next higher form and record those results in the data system.

For post-tests:

If possible, retest immediately using the next higher recommended form and record the results in the data system. DO NOT record the out-of-range test and score.

If immediate retesting is not possible, enter the test in the data system using the highest valid score for the test administered.

Example: Juan scores a 220 on a CASAS 82RX. Because the score is above the accuracy range, enter the test into the data system with a score of 216, the highest valid score.
