Software plays a major role in organized Scrabble activities.
NASPA's Web Committee offers web hosting space to software developers
and works with them to develop standards.
The Technology Committee evaluates and certifies word judge software for use at tournaments and clubs.
NASPA also licenses the NASPA Word List and NASPA School Word List for use by developers. Please
contact us if you would like to use our word list in your application.
Certification and licensing are separate processes; software may be either, neither, or both. Uncertified, unlicensed software is listed here only for information purposes, and not as an endorsement.
