I have an online survey that I want high school teachers to fill out... How do I get to them? Any suggestions?

It is a short 10 minute survey that offers a $10 gift certificate for filling out. I have not been able to get many teachers/professors to fill out. I emailed it to all my old teachers, but that is not very many and they did not forward it to many friends. What do you suggest?

It really depends on what the survey is for. If it is for information about college or a teaching program simply go to the local high schools in the area and introduce yourself. A personal touch is always better. If it is for a commercial site get the mailing addresses from your state database for all the high schools in the state and mail out cards that invite them to the site.
Reply:Perhaps you can email the school board offices or the principals and ask them to help you. They can forward the email with a link to your survey.
