Spache is a readability test for English best for texts up to fourth-grade level. We keep it separate from our primary selection of algorithms we use to calculate our unique and reliable readability score. This is because it's a specialist tool meant for a specific age group.
Spache calculates sentence length along with unfamiliar or difficult words according to a set list of familiar words for young children.
If you have any questions about our range of algorithms, please don't hesitate to get in touch.
