I have just finalised the progress of the year groups and am delighted to see that from December to June 53% of the 98 students using Spellzone have raised their standardised scores to 100 and above.

One of the students has put in a huge amount of effort in completing Spellzone at least 3 times a week since his arrival with us in January. Looking at his scores after the latest GL testing, his standardised score has risen from 99 to 131. This is a truly phenomenal result. I just wanted to share the best result I have ever seen.
