Two Editions – What’s Right for Your School?
- International Edition - British English (NEW)
The International Edition uses British English spelling conventions throughout and is recommended for new schools, or existing Spelling Mastery schools ready to transition to the International Edition. - Current Edition - U.S. English
The U.S. Edition remains available and fully supported. Existing users can continue with this edition to maintain consistency with their current program materials.
