For schools

One short check a month, and the lesson it points to

A twenty minute paper in maths, science or English, built only from what the class has been taught by that month. Every wrong answer carries a named mistake, so the report tells the teacher what to teach on Monday rather than what the percentage was.

1The class sits one short paper

Fifteen questions at Key Stage 2, twenty at Key Stage 3, about twenty minutes. Everyone in the class gets the same paper.

2It only asks what has been taught

The paper is drawn from the units up to that month on the WAJD roadmap for that year, so nothing on it is a surprise.

3Every wrong answer is named

Marking happens on the server. A wrong answer is matched to the mistake behind it, not simply crossed out.

4The report opens with the lesson

The teacher gets the three mistakes to fix, in order, with the lines to put on the board and the names of the pupils who need them.

A report from a class that does not exist

This is the real report, marked by the real code, with invented pupils and invented answers.

Each step is the mistake itself, with the two lines that separate the wrong method from the right one.

1Repeating the operation instead of undoing it
8 pupils: Amina, Ben, Chidi, Daniyal, Farah, George, Idris, Jana
Question4x + 7 = 31
They writeadding 7 to give 4x = 38
It should besubtracting 7 to give 4x = 24
BecauseThe 7 was added on, so taking it off is what leaves 4x on its own
Say this: Every step is undone by its opposite. Always check by putting your answer back in.
2The total given as the mean
8 pupils: Ben, Chidi, Daniyal, Farah, George, Hana, Idris, Jana
Question2, 0, 3, 1, 4, 2 over six matches
They write12
It should be2
Because12 is the goals scored altogether, not the goals per match
Say this: A mean is always smaller than the total. If yours is not, the division is missing.
3Multiplying only part of the bracket
5 pupils: Ben, Daniyal, Farah, George, Idris
Question3(x + 2), with x = 5
They write3x + 2, which works out as 17
It should be3x + 6, which works out as 21
BecauseThe bracket is worth 7 when x is 5, and 3 lots of 7 is 21
Say this: Everything inside the bracket gets multiplied, which is exactly what the area model shows.

Why this is different from a test score

It cannot ask about the summer term in November

The check follows the curriculum roadmap for that year group, so a pupil is only ever asked about work the class has already met. A low mark means something.

A mistake, not a cross

Every distractor is written from a named misconception that is documented in the authored library behind WAJD. That is what turns a mark into a next step.

The same paper, sat once

Everyone in the class sits the same questions, and the first sitting is the one that counts, so the class average is worth comparing month to month.

Free, and it stays free

WAJD Academy is free for families and for schools. There is no per pupil licence and no trial that ends.

Questions a head asks first

How long does the check take?

About twenty minutes. It is fifteen questions at Key Stage 2 and twenty at Key Stage 3, and a class can sit it in a single lesson.

Does it only ask about what we have taught?

Yes. The paper is built from the units up to that month on the WAJD roadmap for that year, so a November check never asks about work set for the summer term.

What makes the report different from a percentage?

Every wrong answer is matched to a named mistake, written out with the two worked lines that separate the wrong method from the right one. The report opens with the lesson to teach next, and says which pupils need it.

What does it cost?

Nothing. WAJD Academy is free to use, and the monthly check is part of it.

What do you do with pupil data?

Marks stay inside the class and are visible to that class's teacher. Nothing is sold, and nothing is shared with anybody else.
