any thoughts on why dd performs higher on standardised assessment at home rather than school?

[billiejeanbob]

we are appealing dds statement through sendist and as a result my dd (8) has been subject to quite a few standardised tests. these have taken place by nhs - slt, ot, LA EP and indie slt, ot and EP.
the standardised assessment that has taken place within the school setting seems to indicate that dd is achieving low scores accross the board (LA EP used the british ability scales, plus nhs slt assessment).

However on two different occasions dd has been assessed at home. firstly was nhs slt (as summer holidays). this indicated that dd has specific areas of difficulty, yet other areas are age appropriate.
Secondly was indie EP as we were fastly approaching evidence deadline and so the assessment took place on the weekend. again the results indicated specific areas of difficulty, yet other areas were age appropriate (despite her complex difficulties). the indie EP used the wisc assessment and the slt used the celf4.

has anyone else experienced this? dd seems to be underachieving on the standardised assessments when taken place in the school setting, yet demonstrating clear ability when they have taken place at home. im confused as to why this is, can anyone offer any advice?

Absence of distraction? ds1 can be very focused 1:1 but the minute something else is going on in the room he loses concentration.

DD is the same. I was present when Dd hsd her latest assessment at school and oh my god, there were so many things distracting her. She was all over the place but not tuned in to the assessment at all.

Home is a quiet place with so much less distraction. As a resukt she actually tunes in to the assessment and tends to score a lot higher.

Another possible reason could be stress as I am sure I have read about studies that show brain function is impaired when you are stressed. Are there any behaviours to show if she is stressed at school. ds2's EP was struck by the difference in the way he presented at school and at home - did not cooperate in tests at either venue but there was a clear difference in body language apparently.

Yes, we experience similar with Dd3, she is very easily distracted.
Also her stress levels are definitely higher at school.

We also have the problem that even though she does score highly on some formalised assessments she isnt able to transfer the skills into the classroom.

It is very difficult isnt it because the LA see the scores that are age appropriate and dont "notice" the very low ones

dd also struggles to transfer her skills to the classroom ineed. we are having the problem where the LA are focusing on the low scores and declaring that dd is globally delayed and therefore does not meet the criteria for SLT and OT .
Dd is very easily distractable so that could be a factor, although I was present during the assessments and she was focused. I think stress factor is a major part of it, as at home she is very relaxed.
thanks for the replies .
