Hi Ralph - the school need to assess a pupil's writing/processing speed or working memory where they are intending to use form 8 to apply for extra time.
If your ds's ASD and anxiety cause him to require the extra time then filling in form 8 isn't necessary.
It sounds like the school may already have sufficient evidence to meet current JCQ regs from your post, but the SENCO will need to follow JCQ regs to present the info (as posted below).
You should also ask for the adjustment to be written into his statement/EHCP at annual review for extra evidence.
p26 JCQ regs:
'Where a candidate has complex needs, i.e.
Communication and Interaction Needs; or Sensory and/or Physical Needs; or Social, Mental and Emotional Needs; which have a substantial and long term adverse effect on his/her speed of processing, appropriate evidence of need (as below) must be available at the centre for inspection.
In these specific cases Form 8 is not required.
Substantial impairment – evidence of need
So as not to give an unfair advantage, the centre’s letter or file note (written by the SENCo) must:
confirm that the candidate has persistent and significant difficulties when
accessing and processing information and is disabled within the meaning of
the Equality Act 2010;
include evidence of the candidate’s current difficulties and how they substantially impact on teaching and learning in the classroom;
show the involvement of teaching staff in determining the need for 25% extra time;
confirm that without the application of 25% extra time the candidate would be at a substantial disadvantage; (the candidate would be at a substantial disadvantage when compared with other, non-disabled candidates undertaking the assessment.)
confirm that 25% extra time is the candidate’s normal way of working within the centre as a direct consequence of their disability.
The centre’s letter or file note is supported with, for example:
a letter from CAMHS, a HCPC registered psychologist, a hospital consultant, a psychiatrist; or
a letter from the Local Authority Specialist Service, Local Authority Sensory Impairment Service or Occupational Health Service†; or
a letter from a Speech and Language Therapist (SaLT); or
a Statement of Special Educational Needs relating to the candidate’s secondary education, or an Education, Health and Care Plan, which confirms the candidate’s
disability. '
