 Alpine Testing Solutions is adept at designing and performing classical test theory, item response theory (IRT), and Rasch analyses to support the validity of test uses, reliability of test scores, and fairness for test takers. Our staff has the expertise to appropriately work with data from programs that use selective and/or constructive response items (e.g. "traditional" and "innovative" item types, scenario and case study items, simulations and labs), dichotomous and/or polytomous scoring, and diverse administration models (e.g. on-demand and windowed, fixed-form, computer adaptive, linear-on-the-fly, testlets).
Examples of analyses provided by Alpine Testing Solutions include:
- item and option analyses
- test analyses
- security analyses (a.k.a. data forensics)
- forms assembly
- reliability analyses
- equating and scaling
- rescoring
- standard setting analyses
- survey analyses (e.g. job-task analysis)
