I am in the School of Edu & just starting my student teaching semester. What we have been told & will be working on this coming semester is our portfolio with teacher samples. According to USC Upstate - it should include anything related to your ADEPT portfolio...ei, Lesson plans, Unit plans, pre/post and any other assessments, professional development/certifications (Darkness to Light, Bloodborne Pathgeons, etc), and anything else that shows grow & development throughout your time in the classroom. Also have your environment plan, organization plan & classroom management plan in there. Yes, how you would communicate with the parents/volunteers should be in there.
Hope that helps, again this is from what our program is preparing us for...however it should help you out.
