Chapter 17 of The Complete Guide to Public Employment describes how to fill out the form in detail. Also attach your resume to the form when you submit it as a reinforcement of your qualifications. Mail to the address in the vacancy announcement. To get on an eligibility list, a test or series of tests may be required. Prepare for a government test by picking up some practice tests published by Arco Publishing at your local bookstore or public library.
Some agencies have handouts giving guidelines for taking the tests.
