Usually you can have a paraprofessional administer the test. Sometimes you can train parent volunteers. It helps if the person is fluent in the language of the student, but that is not always possible. Because the test is so time-consuming it needs to be administered in a quiet place by someone other than the teacher, one-on-one.
It also depends on which state you are in and what test your state mandates you administer to the students. We are administering WIDA this year, the third or fourth test in the last five years. For the WIDA there is an on-line training that you can do to refresh yourself on how to administer it.
Depending on the requirements in your specific school district, the ELPA for the 2011 window opens in Jan 12. It is more preparation to be done as a district PRIOR to the test what is really the part where you have to do the most work.
For example, prior to the window, the school must have a central scoring database to which the students can go and get their score. The test is not computer-graded so they will need a date by where they can go and expect to see a grade posted.
Second, you have to ensure that all the computer microphones are in working condition, and that you have enough headphones for each student for he listening and speaking part of the test.
Third, you have to establish a protocol: What do you do before and after the test? What are the students to before and after? Will they sign in and out. How much time will they be allotted? What are the conditions that may allow a students to repeat the test?
As far as the administration, thats the easy part. The test is student-oriented and the kids will have to provide their own voice samples, and the computer is very good with the directions. You really only have to be there for tech support or to help the students with their accommodations: Do not read the test to them.
