PEARL is a high level procedural programming language, which was especially designed for the demanding need to have an expressive and comfortable language for solving multitasking problems when controlling technincal processes. PEARL is an abbreviation for "(P)rocess and (E)xperiment (A)utomation (R)ealtime (L)anguage". It was designed around 1975 at the IRT Institute of the Leibniz University in Hannover with the idea in mind to have an easy to learn programming language for realtime problems. For more, also historical information please visit (http://www.pearl90.de/). In 1998 PEARL-90 was standardized by the Deutsches Institut für Normung e.V. in DIN 66253-2. PEARL provides the standard data types and structures known from other procedural languages like e.g. ...

The new site is at http://psychometricon.net/libirt/ Library of functions to estimate the items and abilities from the responses of subjects to a questionnaire. The IRT models supported are the logistic model, the multivariate logistic model, the graded model and smoothing by penalization and kernel.

The project aims to provide the open access internet-based computerized adaptive testing (CAT) program based on the 3 parametric logistic model or Rasch Model out of item response theory. It will add item analysis programs based on item response theo

CATEST is a project-based Item Response Theory(IRT) Distributed Testing system. Development platform. Net 2.0 + MSSQL

This project aims to develop open source psychometric data analysis software, including estimation software for Rasch and Item Response Theory (IRT) models for both dichotomous and polytomous test items.

IRT was the once active port of IRM to Perl. Once active being relative to 2001, which was eons ago. IRT development has been dropped in favor of IRM development. We suggest you go to the IRM page here at SF.
