So, I'm 17 and have missed a lot of school lately. They are now threatening to charge me with truency. I live in CO. Can they do that?

I am an education attorney. Truancy laws require regular school attendance, unless the child can be proven to be emancipated or for other explanable extraordinary circumstances. You will need to discuss the facts in more detail for a more appropriate response. Call 303-409-702. This is not legal advise, as I do not have sufficient information and you have not retained this office by this response.   Derry Dale Sadler
