Software For Test Item Analysis For Free Psychometric SoftwareCurrent methods include classical item analysis, differential item functioning (DIF) analysis, confirmatory factor analysis, item response theory, IRT equating, and nonparametric item response theory. Patrick Meyer at the University of Virginia. Item responses (ABCD) and keys are typed or pasted into the workbook, and the output automatically populates unlike some other programs, CITAS does not require any "running" or experience in psychometric analysis, making it accessible to school teachers and professors.JMetrik is free and open source software for conducting a comprehensive psychometric analysis. Software directory at the Institute for Objective MeasurementIn addition, there is an increasing number of packages for R that can be found in the CRAN Task View: Psychometric Models and Methods Classical test theory Classical test theory is an approach to psychometric analysis that has weaker assumptions than item response theory and is more applicable to smaller sample sizes.CITAS (Classical Item and Test Analysis Spreadsheet) is a free Excel workbook designed to provide scoring and statistical analysis of classroom tests. REMP at the University of Massachusetts, USA Important websites for free psychometric software include:IRT methods include the Rasch, partial credit, and rating scale models. Fit statistics are reported along with factor loadings and error variances. Confirmatory factor analysis is limited to the common factor model for congeneric, tau-equivalent, and parallel measures. DIF effect sizes and ETS DIF classifications are included in the output. The DIF analysis is based on nonparametric item characteristic curves and the Mantel-Haenszel procedure. Reliability coefficients include Cronbach's alpha, Guttman's lambda, the Feldt-Gilmer Coefficient, the Feldt-Brennan coefficient, decision consistency indices, the conditional standard error of measurement, and reliability if item deleted. Sandisk imagemate sddr 31 driver for macIt is only available from Assessment Systems Corporation.Lertap5 (the 5th version of the Laboratory of Educational Research Test Analysis Program) is a comprehensive software package for test and survey analyses, developed for use on Windows and Macintosh computers with Microsoft Excel. It also calculates typical descriptive statistics, including the mean, standard deviation, reliability, and standard error of measurement, for each domain and the overall tests. It calculates the proportion and point biserial of each item, as well as high/low subgroup proportions, and detailed graphics of item performance. It is unique in that it produces tech reports ub Microsoft Word rather than ASCII output, with graphics, narratives, and embedded tables. JMetrik requires Java 1.6 on the host computer.Iteman is a commercial Windows program specifically designed for classical test analysis. Technical papers related to the application of Lertap5 are also available.Lertap5 was developed by Larry Nelson at Curtin University and is available fromTAP (the Test Analysis Program) is free a Windows 9x/NT/2000/XP/7 program written in Delphi Pascal that performs test analyses and item analyses based on classical test theory. DIF support modules include scripts for use with both R and R Studio.Users of IRT, item response theory, may make use of four special options: one will produce the data and item control files required by Xcalibre another sets up an ASCII file for Bilog MG a third prepares data for processing with SAS, and will write suitable lines of SAS code for use with SAS IRT modules a fourth interfaces with the Excel version of an R package called "RIRT", allowing users to calibrate items without leaving Excel.Several sample datasets for use with Lertap and/or other item and test analysis programs are available these involve both cognitive tests, and affective (or rating) scales. Mantel-Haenszel methods are used graphs of results are provided, including empirical DIF plots. While having particularly extensive support for classical test theory methods (CTT), Lertap5 also has a Rasch item analysis capability for dichotomous test items.DIF, differential item functioning, is supported. A number of routines for personality, psychometrics and experimental psychology. ViSta has not been updated since 2014R package. Valero-Mora, and Forrest W. It was developed by Ruben Ledesma, J. TAP also provides individual examinee reports of total scores and item responses.ViSta-CITA (Classical Item and Test Analysis) is a module included in the Visual Statistics System ( ViSta) that focuses on graphical-oriented methods applied to psychometric analysis. It provides reports for examinee total scores, item statistics ('e.g.' item difficulty, item discrimination, point-biserial), options analyses, and other useful information. Several functions serve as a useful front end for structural equation modeling. Functions for simulating particular item and test structures are included. Item Response Theory is done using factor analysis of tetrachoric and polychoric correlations. ![]() Estimation is by CML or Bayesian techniques. The central IRT model is a polytomous generalization of the extended marginal Rasch model. Many psychometric methods not found elsewhere are provided, such as Haberman’s (2007) interaction model generalized for polytomous items, efficient generation of plausible values or scores, new methods for exploratory and confirmatory DIF analysis, support for the 3DC method of standard setting, and many more. The package includes facilities for importing and managing test data, assessing and improving the quality of data through basic test-and-item analysis, fitting an IRT model, and computing various estimates of ability. It is commercial, and only available from Scientific Software International.Dexter, first published February 2017, is an R package intended as a robust and fairly comprehensive system for managing and analyzing test data organized in booklets. ![]()
