See progress. Shape what's next.
A SEND continuum platform that connects progression, assessment and planning; turning evidence of progress into purposeful next steps for teaching.
Progress doesn't always happen in age-related steps.
For pupils with SEND, meaningful learning can happen between traditional milestones. Conventional assessment systems are often designed around broader measures of attainment, making smaller steps of progress difficult to see.
When progress is difficult to see, it becomes harder to show what a pupil has achieved, identify meaningful next steps and make assessment useful for teaching.
Arc XII gives schools a clearer view of progression — and a practical way to use it.
Progress should lead somewhere.
Arc XII brings progression, assessment and planning together, helping practitioners use what they learn about a pupil to shape teaching.
See where learning starts. Recognise progress as it happens. Use that information to shape what happens next.
One platform. Three connected parts.
Arc XII brings progression, assessment and planning together in one connected approach.
Continuum
See progression more clearly.
The Arc XII A1–A12 SEND continuum breaks learning into meaningful stages, giving practitioners a clearer picture of where a pupil is working and the progression that comes next.
Assessment
Build a meaningful picture of progress.
Establish a clear starting point, record Emerging, Developing and Secure judgements, add supporting evidence and see how progress develops over time.
Planning
Turn progress into teaching.
Use assessment information and appropriate Arc XII objectives to shape personalised teaching and planning around what the pupil is ready to learn next.
See the whole progression picture.
Arc XII shows progress in context, not as an isolated score.
Establish a starting point
Baseline pupils against the continuum and create a clear reference point for future progress.
Recognise progress over time
See how assessment develops over time rather than relying on isolated snapshots.
Keep the evidence connected
Add supporting evidence alongside professional judgements so the story behind progress remains visible.
Shape what happens next
Identify appropriate objectives and carry them into teaching and planning.
Built to support professional judgement — not replace it.
Professional judgement stays with the practitioner. Arc XII makes the picture clearer.
Arc XII Complete
Spend less time planning from scratch.
Arc XII Complete gives practitioners access to a comprehensive, continuum-linked planning library — providing a purposeful starting point that can be adapted around the pupil.
Less time searching and writing. More time adapting, resourcing and preparing learning that works.
