The Test Validation & Analysis Program (TVAP) includes two
Excel Workbooks that are designed to be used by personnel professionals
to aid in developing and validating written tests that address
professional standards, the Uniform Guidelines on Employee Selection
Procedures (1978), and relevant court cases. The Workbooks include
macros, surveys, and formulas that address the standards applied
in Contreras v. City of Los Angeles (656 F.2d 1267. 9th Cir.
1981) and U.S. v. South Carolina (434 US 1026, 1978).
- 50-page Instruction Manual including directions, references,
and appendices (including a Manual for writing better test items
and for conducting effective Angoff Panels).
- Test Item Survey that can be completed by subject-matter
experts to gather validation evidence for written tests (14
questions are included that are designed to address testing
standards, the Uniform Guidelines, and concepts derived from
test litigation).
- Test Item Survey Workbook (Excel workbook with over
10 programmed sheets) that can be used to input data from the
Test Item Survey, tabulate the results, and screen test items
for addressing specified test validation criteria.
- Test Analysis Workbook which is used for inputting item
Angoff ratings, setting a "critical score," conducting
rater reliability and rater panel reliability analyses (and
"outlier" raters), importing test score data, conducting
item analysis (including point-biserial, item difficulty, and
differential item functioning analyses to analyze test item
bias), and test-level analyses (including Cronbach's Alpha,
Kuder Richardson or KR-21 reliability, mean, standard deviation,
classical standard error of measurement, and conditional standard
error of measurement), setting a modified Angoff cutoff score
using the procedure followed in the U.S. v. South Carolina case,
and analyzing the cutoffs for adverse impact using the Fisher
Exact statistic and practical significance tests.
