Consultation concerns

I am new to this site and apologize if this issue has been discussed before. I haven’t yet explored the whole site. Anyway, summer is here, time to relax, but this gives me time to reflect. I feel that one of the areas I need to work on as a teacher is consultation with general ed teachers and would appreciate any advice. I am an elementary special ed teacher. I do both pull out and inclusion. I try to work with the teachers to discusss modifications and accommodations but at times I feel they just “yes” me and then do what they want. This is also the case with the paraprofessionals. I have even had a situation where the teacher knew I was willing to create a modified test, claims she forgot to tell me, gave the child the classroom test which she failed and forgot to tell me….I could go on and on. I thought I wouldn’t have to go over the IEP’s again and again, but maybe I do. I even provide the teachers with separate lists of modifications…believe me they are basic…I want to work with the teachers…any suggestions. Thanks in advance.
