Traditional IRA withdrawal for Education?

I read somewhere that one can take withdrawals penalty free from a traditional IRA for 1), a first time home buy, or 2) for education expenses.

 

Can someone confirm if the second option, for education expenses, is true? I have a daughter in college, a son in private school, and I have also started going back for a Master's degree, and it would be nice to know if this is a viable source to tap, if needed.

 

If true, what are the limits, and any restrictions.
