The California Achievement Test (CAT 6) •	The California Achievement Test (CAT 6) reliability is based on the KR-20 internal-consistency estimates. Authors provide internal-consistency coefficient for individual subtests at different levels of the CAT/5. some subtests are too low for use rendering it challenging to make decisions in regards to personal students •	On the validity of the measurement, the data on various forms of various kinds of the validity of CAT/5 tend to be limited to the illustration that the percentage of students mastering objectives raises with age with a report correlation of CAT/5 with TCS/2. •	On the normative procedures, the norms for the measurement are questionable. The reason is that of the lack of provision stratification information for the level 11 students who only 4,161 students participated for the winter standardization. •	On the biasness of the measurement, the data seems to be limited to internal consistency making it unsuitable for screening(National Learning Corporation, 2008)
