When using pages like Students > Assessments > Summative Tracking and My Items > My Classes, the date will auto-fill to the last day of that assessment period.
For example, the last day of the Summer assessment period is 21st July.
All the students in the marksheet will have a current enrolment for 21st July. If you off roll a student with an end date of before 23rd July, they will no longer appear in the marksheet.
For example, Callum Allen in this marksheet:
Once the student is off rolled with an end date of 16th July, they will disappear from the Summer marksheet.
The student is no longer on the marksheet.
How do I get the student on the marksheet again?
The student's leaving date is incorrect
Follow this article to change their end date.
The student's leaving date is correct
If their end date is correct and wasn't a mistake, every time you open up the marksheet, you will need to change the date to before the student's end date. In this example, changing the marksheet date to 15th July will make the student appear again.
