For overall NAPLAN results ranking, only the schools participated in all the tests are ranked (based on the average score). If you cannot find your school in the list, try a page or a list with different subject or grade. The school should be listed if the school participated in the test or all the tests in the case of overall ranking.

Are you looking at the top school lists? Probably the schools doesn't belong to this list. Try the School Rating or Compare Schools pages. For example:
