About Tangerine

Tangerine®  is electronic data collection software designed for use on mobile computers, including netbooks, tablet computers and smartphones. Its primary use is to enable capture of students’ responses in oral early grade reading and mathematics skills assessments, specifically Early Grade Reading Assessment (EGRA) and Early Grade Mathematics Assessment (EGMA), and interview responses from students, teachers and principals on home and school context information.  

The Tangerine approach improves data quality and the efficiency of data collection and analysis by simplifying the preparation and implementation of field work, reducing student assessment times, reducing measurement and data entry errors, and eliminating manual data entry from paper forms. 

Tangerine was developed in 2011 by RTI International with its own internal research funds, and made available to the public through a GNU General Public License.  This means that Tangerine's source code is available for anyone who wishes to install and use Tangerine on their own web server.  Tangerine's code and related documentation is available on Github, a commonly used repository for open source software.  To learn more and have a look under the hood, check out Tangerine's Code Repositories on Github.
