A solution to improve every learner: the data that proves the impact

What is Standard Age Score (SAS)?
Standard Age Score (SAS) combines a learner's raw test score for their age and test difficulty, placing it on a scale for comparison with learners nationally. A score of 100 is average, indicating a learner's reading ability matches what is expected for their age. Scores below 100 mean a learner is performing below age expectations, while scores above 100 indicate higher performance. The SAS allows fair comparison of learner performance within and across year groups, helping track progress effectively.

The question for our schools in the Trust has to be, if you're not teaching vocabulary, why not; and if you are, why are you not using Bedrock?

In a year with Bedrock embedded into our whole-school literacy strategy and learners completing their Bedrock regularly, we saw an average 14-point SAS increase across our reading tests.

Working as a literacy lead can be isolating; Bedrock holds you up and champions you.

Using Bedrock as a class-based, whole class language instruction model for 12 weeks has been transformational not only for the quality of teaching but for pupils' outcomes.
