SLCC develops new versions (forms) of the CDAL examination on a regular basis and administers them during two testing periods each year. Each version is based on the knowledge that executive directors of assisted living communities are expected to have, as validated in the job analysis study conducted in 2015. Each version has 135 questions that are scored and 15 that are included for experimental purposes. Candidates qualify to take the test by satisfying eligibility criteria that address education and experience in the management of assisted living communities. Scores are scaled to a range from 200 to 800, with the passing standard anchored at 500. The passing standard was established using methods that link the required score to the level of proficiency that corresponds to certification. The following table presents information about CDAL candidates have performed on the test.
|CDAL Examination Statistics||Form||Number Testing||Number Passing||Percent Passing||Average Score||Standard Deviation||Passing Standard||Internal Consistency||Decision Consistency|
Elements of the Table Defined Window: Candidates for the CDAL examination can take the test during two two-month periods each year. Form: The version of the test. Number Testing: How many individual candidates took the form. Number Passing: How many individual candidates achieved a score that is high enough to pass. Percent Passing: The number passing divided by the number testing. Average Score: The average scaled score achieved by candidates testing in a window on a form. Standard Deviation: How widely dispersed scores are around the average. About 68% of the scores lie within +/- 1 standard deviation from the average score. Passing Standard: A criterion-referenced standard that is applied to equated scores for all forms. SLCC established this standard using the Modified Angoff Technique in 2016. Internal Consistency: An estimate of the reliability of candidates’ scores, determined using the Kuder-Richardson 20 computation. The statistic ranges from 0 to 1, the higher the better.
