Deliberate ‘failure’ with Year 6 school work?

Hello!

My son is in Year 6. Up to the start of Year 6, he was consistently achieving very well in all aspects of his school work right from starting school. In the last few months, however, his scores in English have dipped considerably to this week not even an age expected score in SATS mocks. He is a capable student, and often achieves perfect scores in maths. He claims to not to be able to read, that he can’t spell, yet his prior achievement in school and when doing homework or reading with me, does not bear this out. He’ll go from using more complex language with a high degree of accuracy, such as ‘spherically’, to consistently writing ‘tabel’, even after I’ve corrected this.

His teacher, the SENCo and I all think that there’s an element of him deliberately trying to almost ‘fail’ in all other aspects of written school work apart from maths. 
None of us have come across this before - his dad and I are also both highly experienced teachers. We’re at a loss of how to support him.

I’ve been trying to find something online which discusses this but with no luck, so am wondering if anyone else has had this experience or can point me in the direction for support?

Thank you for reading this.

  • This sounds really tough - and honestly, you're not alone. What you're seeing (sudden "I can't read/spell" at school, perfect at home, maths untouched) is a classic sign of autistic masking burnout mixed with demand avoidance (often PDA-style). High-achieving kids like him hold it together for years, then Year 6 hits - SATS pressure, secondary transition, "prove you're clever" - and the mask cracks. Writing/English feels most vulnerable: visible, judgmental, no "right" answer like maths. So the brain protects by declaring "can't do it" - strategic shutdown, not laziness.

    Parents on forums [removed by mod] call it "academic avoidance" or "perfectionism flip": he knows he's capable, but fear of "not perfect" makes him sabotage. [removed by mod] Year 6 son went from top English to "tabel" overnight - same pattern. Once pressure dropped (no corrections, optional writing), he bounced back.

    Quick supports to try now:

    • Zero-demand English phase: Tell him/school: "No marks, no expectations for 2–4 weeks - just read fun stuff, dictate if you want." Reduces anxiety loop.

    • Home-only proof: Do short, silly writing (e.g., "write a note to your favourite game character - no rules"). No school link. Builds confidence quietly.

    • Visual/choice framing: Use timers or pictures for steps, let him pick: "Type or say? No handwriting today."

    • SENCo push: Share this as "masking burnout" - not defiance. Ask for low-demand plan + dyslexia screen (to rule out). If PDA traits, look at PDA Society resources - they have school guides.
