Software

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.

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.
