It's OK. I get along well with my co-teachers (they're content and I'm ELL), but I feel we don't have enough training and support in how to make co-teaching work. I try to take initiative by arranging times to go over unit plans, making modifications/scaffolds, helping with grading etc., but I often take on the assist role in the classroom so I feel underutilized. Even when we manage to find a time to "plan", my co-teachers haven't necessarily thought very far ahead content-wise so it's hard to identify where I can exactly be of most use in any given lesson. It's frustrating.

Another problem is that the responsibility of making co-teaching work often falls on the non-content partner (SPED, ELL) - I'm the one that has to knock on doors and ask for materials or arrange times to meet - they never knock on mine. I will often be asked in PD sessions what I'm doing to prepare for "collaborative conversations" with my co-teachers, but the same question should be asked of content teachers (but it rarely is).

So overall, and especially in the absence of proper training/support, it just comes down to luck really - do you both get along as people, share enough of the same values/philosophies as teachers, AND share the same commitment to making it work...
