Lertap 5 welcome

Lertap is a software system used to process and analyze data collected from quizzes, exams, tests, and surveys. Lertap is an acronym for the Laboratory of Educational Research Test Analysis Package.  It dates way back to 1973.  

 

Lertap 5, the latest "genre", works with Microsoft's spreadsheet program, "Excel". There are versions for Macintosh and Windows computers.

 

A screen shot of a typical Excel worksheet set up to work with Lertap 5 is seen here:

A quick overview of how Lertap 5 operates, and samples of the reports it produces, may be seen by looking at this set of slides. (Also available as a PDF file.)

 

Lertap 5's forte is item analysis and test scoring. The majority of the statistics it produces are solidly based on CTT, classical test theory. It will handle polytomous cognitive and affective items (such as rating scales), with extensive support for partial-credit item scoring. A virtual cornucopia of charts and graphs is a salient feature of Lertap 5.

 

Users may tailor Lertap 5's operations and output by setting their preferred options in the "System worksheet". A display of part of this worksheet is provided below:

The next page, "Features", has more information on many of Lertap 5's capabilities.

 

Lertap 5 is free for students to use; it may be "purchased" (for free) by using the e-store mentioned in link 7 below.

 

A paper discussing and comparing some of the features of three free (for students) item analysis programs, Lertap 5, SAS University, and jMetrik, is here. The paper also makes mention of Iteman, Xcalibre, and Bilog-MG.
