I have a y9 and a 19yo.
It partly depends on the school and how 'big' the tests are.
First and foremost, I would say setting up good habits for the future. So:
- All tests should be revised for
- Revision should not be left until the day before
After that, this is what we do:
- DD comes home and says she has a test coming up
- I check she knows the date and what it will cover
- we discuss what revision is needed, e.g. history assessments tend to need only a small amount of specific knowledge but then also to understand question answering technique to be reviewed, whereas science is mainly content, maths is practice etc.
- we have a chat about when she will do the revision, and I normally get involved too.
- for us it is a compromise. dd2 tends to do less than I would like as she gets tired and/or bored quickly. I have to pick my moments!
Y7 is a good time to practice different techniques
- revision cards
- mind maps
- using BBC bitesize
to find what works well for your DC and for different subjects
You shouldn't go too over the top in y7 because things will only increase.
When the DC gets results of the test back, have a chat about what worked / what didn't. Sometimes DD gets low scores, but when I see the questions I understand why (e.g. limits in her ability rather than revision).
If there is a 'test week' you need to be more organised because of prepping a number of subjects at the same time.
Don't assume your DC will just 'get' how to revise without help. You testing as they learn will help them see whether they really know something or are just fooling themselves.
For my DD we mainly use revision cards that I write and me testing her. Occasionally we use BBC bitesize. For maths I set her questions. We are probably unusual in the level of 'hands on' she needs.
