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.

Overview

At Bedrock, we're relentlessly committed to transforming young people's outcomes through cutting-edge PedTech.

Founded and led by teachers, we understand the transformative impact of exceptional teaching, and the challenges educators face. That's why we've leveraged the latest in learning design, neuroscience, and real-world experience to deliver an adaptive, personalised and interactive learning journey that liberates learning - unlocking curriculum access to prepare every learner for tomorrow's world.

We're more than a platform; we are experts in education, giving over 1000 partner schools the tools and expertise they need to drive real, measurable progress. When schools invest in Bedrock and implement it effectively, the results are not only impressive – they're inevitable. In this case study, we showcase the compelling data from our partner schools to prove it.

The results speak for themselves

On average, learners who complete one 30-minute Bedrock lesson per week improve by 5 SAS points in just 6 months.*

*Based on Bedrock Reading Test (BRT) data for 1,366 learners who completed at least 1 Bedrock lesson per week and took 2 BRTs within 12 months (averaging 6 months apart).

This isn't an anomaly: Bedrock works. From urban academies to rural schools; from KS1 to KS4; the data proves that our approach consistently and significantly drives attainment for every learner. Bedrock isn't about quick wins; it's about sustained, long-term progress that transforms educational outcomes. With continuous, high-quality literacy instruction, learners can expect ongoing growth that compounds over time. A 5 SAS point improvement in just 6 months* is impressive. But it is also only the beginning.

These results extend far beyond reading scores. Bedrock empowers success across the entire curriculum; throughout learners' educational careers; and further, into their professional careers - from landing their first job to securing that life-changing promotion.

Yes: the evidence is clear. Consistent use of Bedrock yields measurable literacy improvement, equipping learners with the fundamentals they need to take their rightful place in society. In this way, an investment in Bedrock is an investment in our young people's futures - promising every child the huge and equal opportunity to achieve their full potential.

Measurable impact: tracking literacy gains

At Upper Batley High School in West Yorkshire, Bedrock is more than just a platform – it's a driving force behind their whole-school literacy strategy. With KS3 learners completing two 30-minute Bedrock lessons each week, engagement is strong. Weekly leaderboards and rewards fuel motivation, and many exceed their targets.

The impact speaks for itself, with Bedrock's pre- and post-test data showing an average improvement of 22% across the cohort. EAL and SEND learners have progressed even faster. More importantly, these improvements are reflected in written work, with students using more precise and sophisticated language.

Bedrock's explicit instruction has also helped develop a broader reading culture. When 50 Year 9 students trialled the platform in their reading lessons, 47 of them preferred Bedrock to an alternative solution – thanks to its deep and engaging approach to learning.

Every teacher is a language teacher

Beyond the statistics, Bedrock has catalysed a huge culture shift amongst teachers – particularly within the Mathematics and Science departments. Across disciplines, staff are embedding literacy into all aspects of school life – praising the platform's accessibility, award-winning customer support, and actionable real-time insights (at both a macro- and micro-population level). By powering literacy at a whole-school level, Bedrock achieves proven impact to set every learner up for success and enable schools to embed an evidence-based disciplinary strategy.

Powering whole-school literacy strategy

At Carlton Bolling in Bradford, literacy is not confined to the English department: it is a strategic, school-wide initiative designed to give every learner the tools they need to excel. By aligning the curriculum across all subjects, the academy ensures literacy development is embedded into every lesson. This means learners aren't just absorbing knowledge – they are actively engaging with subject-specific language, enabling them to read, write, speak and think like historians, geographers, scientists and more.

This approach is underpinned by Bedrock Mapper, our Tier 3 subject-specific language solution used to interleave language across disciplines. By revisiting and reinforcing key concepts in different subjects, learners can apply knowledge in more meaningful ways. The result? Stronger comprehension, more precise communication, and greater confidence across the curriculum.

With Bedrock's real-time insights, teachers can track progress in real-time to give every learner the support they need to thrive. This holistic disciplinary literacy strategy has already delivered an average 14-point SAS increase across reading tests – proving that when literacy is prioritised across the curriculum, the impact is transformational.

According to Jennifer Webb, Director Literacy at Carlton Bolling: "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."

A scientific approach to disciplinary literacy

The STEP Academy Trust partnered with Bedrock to trial a 12-week pilot at Angel Oak Academy. To measure the platform's impact, a test group of 30 Year 4 learners trialled Bedrock, while the control group followed standard teaching approaches.

The results were impressive. Learners in the test group showed significant improvements in their reading comprehension, gaining an average of 7 SAS points versus 0 within the control group. Pupils also reported increased selfworth and confidence due to their academic progress. Within Science tests, this translated to a 30% improvement in scores versus the control, showcasing Bedrock's impact on learners' understanding of key scientific knowledge.

Bedrock has now been implemented across Years 4 & 5 – with Trust-wide expansion coming next. For Professor Tim Mills MBE, the Trust's Executive Director of Primary Education: "After seeing these results, it was unethical not to implement Bedrock as part of our postphonics curriculum strategy."

Real stories, real transformation

The power of consistency

At Sidney Stringer Academy in Coventry, regular use of Bedrock bore impressive results. Pre- and post-test data showed an average improvement of 42% across the cohort – a result which was replicated across the PP micro-population. Meanwhile, a spectacular 48% improvement was achieved by SEND learners. This underscores the significant impact of explicit vocabulary instruction in boosting language skills and academic progress, driving transformational outcomes.

A platform for every learner

At Stanchester Academy in Somerset, reading test data shows that over the course of the academic year, learners who engaged consistently with Bedrock improved by 3.09 SAS points more than those who did not. This was particularly pronounced within Year 9, as well as among PP, SEND and EAL learners, who achieved above-average progress. This proves that the regular use of Bedrock accelerates literacy development - especially for those who need it most.

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?

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.
