Consider running a card-sorting or similar exercise to determine how your users group the information and why. Also, if the school has a current portal, check any analytics data to see what is visited most often or searched for. Combining these 2 approaches will yield a big chunk of learnings to inform your design decisions.
If you can share more about categories or list them, it is a little difficult to rightly suggest without categorizing the features.
But the basic logic remains same.
1) Categorize the interaction that can be put up together.
2) There is always a progressive feature grouping that can be done for future needs or addons.
