Plugins
Here are my PowerSchool plugins and some that I recommend.
The Cluttered Desk
These were developed based on what I thought might be useful.
The current enrollment plugin adds the current enrollment record to the bottom of the Course Registrations page. The intent is to make it easier when you are aligning section registrations with enrollment entry dates.
There is a wide range of reports, plugins and customizations available. There are a large number of free options available and some other more elaborate options in their paid section. The cost of the paid options depends on the number of students you serve, but was very reasonable considering the amount of time it takes to develop and maintain them. Rather than list all of them here, or even try to pick my favorites, it would be best for you just to check them out for yourself.
