Spelling Tutor teaches the 1,000 most common words, which is 90% of the words we use every day.

In order to spell correctly you need to memorise the spelling of each word. You can't use phonics to know if sheep should be spelled sheep or sheap, you have to remember.

The children that have used Spelling Tutor have absolutely loved it! We’ve found it particularly useful for our older children that have done all our other interventions to death.

Writing is the best way to learn spellings, so Spelling Tutor dictates words and sentences for children to write out by hand.

Spelling Tutor then uses spaced repetition, to retest words that were spelled incorrectly over a few weeks. Using this unique formula children make impressive gains in spelling.

In order for a word to be marked as learned, the child has to get it right 7 times, over 21 sessions. This transfers the correct spelling to long term memory.

Children mark their own work, taking complete ownership for their learning.
