i can only tell you how i did it 2 yrs ago when i needed a job closer to home: i checked out the good districts w/in a 15 mile radius, filled out any online application, but also sent a resume to every principal, superintendent and director of curriculum in each district, even if there weren't any specific job postings. i sent out 70+ resumes, but b/c i sent it to the director of curriculum (which not many people do), i was called in for an interview and subsequently beat out 400 other people for a job.
i've heard that in jersey there are between 300-500 resumes per job posting.
good luck to her!
