This can occur when the Signup Date for enrollment is set to a future date. Follow the steps below to check this.
1. In onRecord > Settings > Course Request Setup
2. Select the correct year, category and school level.
3. Edit the Signup Date and change the value to today's date.
Note: You'll also want to make sure you're looking at the student grade level for the next school year. So, if a student currently has a grade level of 8 this year, they won't be able to view course requests until grade 9 in Course Request Setup has current dates.
