Quick tests
Meaning / construction test
Is the expression naming a person, or describing the act of leaving?
If yes: Use “dropout” for the person and “drop out” for the action.
If no: Check the grammatical role; the closed noun and open phrasal verb are not interchangeable spellings of the same form.
Caveat: The distinction is grammatical: noun versus phrasal verb. Preserve the appropriate form when inflecting the verb.
