The checkpoints

What should be visible by when.

The part

What it is

Early checkpoints measure exposure and behaviour change rather than perception, because perception will not have moved yet.

Having intermediate measures is what allows the work to demonstrate progress before the outcome measure moves.

The smallest level

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
