One of the big problems computer science teachers face is the lack of consistant certification requirements. There is a major lack of understanding about computer science at the state level in most states. Chris Stephenson over at the CSTA blog lays out the problems in some detail. Chris is looking for comments and suggestions from teachers from around the US as the CSTA works on a plan to address this issue at a national level. If you are a computer science teacher who is concerned about teacher certification you really should drop by and leave some suggestions. If you are not a teacher but want to understand the issue Chris's post is a great place to start.

BTW CSTA is the Computer Science Teachers's Association - if you are a CS teacher you really should be a member.
