New users start by downloading the free "Mini" version of Lertap. This is done via this webpage. There's a version for Windows users, and another for those using a Macintosh computer.

 

The free Mini version will meet the needs of quite a number of users. It includes all of Lertap5's features and options, and allows for any number of test or survey items to be processed -- its limitation is that it will not process more than 250 data records. A license is only necessary when users want to process more than 250 records. Note: as of April 2021, 4-month limited-term licenses became free for many users.

 

A license may be requested by using this page.
