How to Blend the Online Academy With In-School Provision

A Midlands school has run a blended model for two and a half years — 1,300-plus lessons, seventeen pupils, feedback positive throughout.

Schools too often treat online and in-school provision as either/or. Each alone leaves a gap: the academy can lack the in-person anchor; in-school AP can lack subject breadth. The pupils fall through the seam between them.

The approach

Castle Rock has run the two together. Over two and a half years it has delivered more than 1,300 lessons across the online academy, in-school alternative provision and stretch support for seventeen pupils, with feedback from students positive throughout.

The challenge in context

A blended model gets the best of both: the breadth and specialism of the online academy, with the relationship and routine of in-school provision. The strands cover each other's weaknesses rather than competing for budget.

Sustained over two and a half years, the blend becomes a settled part of how the school supports its pupils.

What changed

The headline is endurance: a 1,300-lesson partnership that has held its quality across years and seventeen pupils, with consistently positive student feedback. That breadth-with-longevity is exactly what other schools find hardest to build and most useful to copy.

“The feedback from your students has been positive throughout.”

The playbook — how to run it yourself
  1. 1Run online and in-school provision together, not as either/or.
  2. 2Use the academy for subject breadth; use in-school AP for routine and relationship.
  3. 3Add stretch support so the model serves more than just catch-up.
  4. 4Sustain it — a blended model proves itself over years, not weeks.

The lesson for schools weighing online against in-school provision: stop choosing. Blend them, let each cover the other's gap, and give it the years it needs to settle.
