This is something that you should discuss in school.  Different frameworks use different terminology and individual schools may interpret terminology in different ways.

The terminology in use for a framework is shown on the tiles, as you can see in the example below:

In general terms, Red Tile < Yellow Tile < Green Tile. Some frameworks also use a Blue Tile which shows higher attainment than the Green Tile.

Some frameworks have additional guidance to help you make your assessment judgements. This can be accessed by clicking on this icon on an objective.
