Stages of development v. Common Core Standards v. Curriculum Scope and Sequence v. Hierarchy of skills: Which do you think is important when teaching students with hearing loss? What will be your focus as the student expands and progresses in skill?

I think all of those are important when teaching any student whether they have a hearing loss or not. I know what you follow with some students may not be on grade level but you still need all of those to know what the child is supposed to be doing or learning and what you as the teacher is supposed to teach. The stages of development charts are great to get a general idea of what children of a specific age can do overall or should be able to do. The Common Core Standards are established as what teachers are supposed to teach the children and they should be able to do it by the end of the year. I know there is a lot of debate over that currently, but hey you have to give it to them for at least trying! I don't know what all is pointing at it failing, but I feel like the idea should not be thrown away. I guess we will see what happens! The other two I feel are more specific to what your district is teaching and those are of course always important. I feel that you should dip into all of these to teach and not just follow one or the other.
As a student expands and progresses in skill I feel that it is our job to move up with them. If they are mastering a skill for their present grade level then you start shooting for skills above their grade level.
