This has nothing to do with the end of your contract (job expires end of school year, Coronavirus / school closure aside)..
Per that contract, you were never supposed to be working in the summer, so you can't collect unemployment.
If you had another contract for summer work and that was cancelled, you can possibly get PUA.
(small edit- there was no contract in my case,(it's month to month)) it's pretty clear from the questionnaire sent that it's not necessarily contingent on whether I was supposed to work in the summer,but rather if I can expect to return to the same job after vacation,
If one is let off indefinitely in June,it would appear its no longer considered vacation period between successive terms

: What constitutes reasonable assurance if I am a ‘regular’ employee?
A: You would have reasonable assurance of a job, if you receive:
A letter for hire
A letter for re-hire
Verbal assurance that you are to return to work for the following term
Or
If you have a history of re-hire (unless you have been told that you will not return) AND you can expect to earn at least 90% of the prior term's wages and benefits
