One of my tips for new users is that you don't need to create loads of aspects. In fact, it's a mistake to create too many. You can create a whole school system from just three aspects for each subject. For example:
Maths Attainment
Maths Target
Maths Progress
(where Maths Progress is a grade aspect that is a 'traffic light' column and can contain only +, = or -)
Create a result set for each term of each year (eg Year 5 Autumn Term) and pair it up with the relevant aspect to create your template.
Don't forget that KS and FSP results should be in your system already so don't create extra aspects for them.
By all means download the Capita tracking marksheets, but remember that they're not easy to adapt if they don't fit your school - you might be better off learning all you can from them, then creating your own.
