Official websites of schools and universities are always hard to do. There's always a lot of things going on, and you have to cater to different kinds of users.
You have to provide information for those who are considering enrolling in your learning institution, and since that entails business, a lot of marketing thought goes into it. You present the courses you offer, pricing, and other important details alongside perfectly posed photos of students of diverse races and cultures. You word the copy carefully to convince visitors that this school's the one for them.
You also have to cater to the students who are already enrolled in your school, and provide them with a user-friendly, easy-to-navigate portal to whatever they may need from the site, from grades to Zoom links to extra-curricular activities.
These diverse objectives often lead to clutter but some schools do manage to pull it off successfully, like Douglas College in New Westminster, BC, Canada.
Their website may not be the best-looking, but it's pretty clear and straightforward, and most importantly, quite easy to use. Check it out here.
