## What is LEST?

The Letter Sound Test (LeST) tests a person’s ability to sound out single letters and letter combinations. 

- Run a LeST test session in under 10 minutes. 
- Automated percentile and z-score calculations for graphemes.
- Practice marking before you buy.
- Hear correct pronunciations of all the letter-sound combinations before you buy.

More about the LeST:
In order to be able to sound out words, we need to know which sound a letter or letter combination corresponds to. 

The LeST evaluates which  letter(s) a person can sound out in isolation (i.e., not in the context  of a word or nonword). 

The LeST is a simple reading aloud task and contains 51 graphemes  (single letters and letter combinations). This test can be administered to individual students.
At the end of the test, the tester gets an overview of the grapheme a reader can sound out in isolation. The tester may then decide to train  the letter-sound-correspondences for the letters that the reader could not sound out correctly.

This app has been developed from the LeST literacy assessment tool created by Macquarie University Centre for Reading.
