Can I sue the board of education for a faculty member sexually harassing my 17 year-old daughter through text messages?

First, as the father of two daughters, please accept my sympathy.

Yes, you should be able to sue the district, the school, and the teacher himself for this behavior. If you daughter requires counseling or other medical or therapeutic support, you may be able to collect for it; depending on the circumstances (e.g. whether there was any prior warning or notice), you may also be able to recover punitive damages.

You should not delay--there are typically shorter time frames for suing government bodies, including schools, than private businesses or citizens. Consult with an attorney with experience in sexual harassment cases and/or litigating against schools; he or she can evaluate what you case may be worth and, if you want to proceed, get the ball rolling. But again: do not delay, and good luck.
