Classical Test Theory Item Analysis

itemanalysis is an R package I specifically compiled for an intro measurement class I teach. It is customized based on the content and concepts I cover in that class about Classical Test Theory Item Analysis. It has two simple functions to run classical test theory item analysis for multiple-choice test items and polytomous items (e.g., rating scales). It also provides empirical item trace lines. The statistics reported in this package can be found in any classic measurement textbook,
