Don't worry about Ofsted, unless you are SLT. You need to know two things: what the state of your subjects is, and what the school plans to do to improve.
Spend a little time setting up your subject file. You might find it easier to have one file with separate sections for the two subjects, and carry out the same tasks for both subjects at the same time, as they are closely linked.
Your school may have a Subject Co-ordination policy to tell you what to include. If not, start with:
School Development Plan
Highlight references to your subjects and any relevant cross-curriculum targets, e.g. for improving outcomes for particular pupil groups
Subject Policy
Long-term curriculum/topic/ subject plan
Create the following:
Subject Audit, i.e. current state of your subjects
What evidence of your subject is there in classrooms and the rest of school, e.g. in books, displays, resources, Assemblies, Trips, visitors, clubs?
Talk to teachers: who has done something interesting, who is not very confident, what would they like to see happen?
Subject Development Plan
One task per half-term. This term's tasks are to set up the file and the subject audit. Then start to address the gaps you've found or your subjects' contribution to School Development Plan.
Diary
Everything you or anyone else in school does connected with your subjects
Then keep collecting evidence/ useful thing: assessment data, planning examples, photos of displays, examples of work, record of pupil discussions, training, resources, useful websites...
Make sure you discuss your subjects in your Performance Management Review.
What is the school's and your vision of where it is going and what needs to be done along the way?
Does anything need to go into the next School Development Plan?
