Node-cat , a Javascript implementation of Computer adaptive testing.

Node-cat is an CAT (Computer Adaptive Testing) Implementation for Javascript Written in nodeJS

Goal : An Open Source Implementation of Multidimensional Computer adaptive Testing using the item Response Theory Methodology.

How it works

Node-cat is a framework for developing applications that require CAT and IRT methodologies in the application logic. Whether you are grading some class notes ... ...Or Writing an application for grading Standardized Tests for Thousands of users.

Two roles are featured in the API , test administrators, and test takers.

###Create a Test according to the IRT methodology

###Defining Item banks and estimating item parameters

###Suscribing Users to tests, And making tests available.

###Using the item retrieval and response API

Instalation

Underlying Technology and Development

Node-cat is developed in the framework of the SICS Research group. Statisticians, Mathematicians and Computer Scientists devoted to produce the world's fastest Item Response Theory Applications.
