give brief consise summary notes and further explanation thank you

Should I take into consideration a student disability when measuring their performance in my classroom? Can I disagree with the identified accommodation, outlined on the student's accommodations letter? What types of accommodations/services are available? Is there a recommended syllabus statement I could use?What can I expect regarding a student's behavior? How are accommodations determined by the Office of Disability Services? Is a student's disability confidential? What if I suspect a student might possess a disability, but has never self-disclosed? What if a student tells me they have a disability, but they never provide me an accommodation letter from the Office of Disability Services?What role does the student play in the accommodation process? What role does the instructor play in the accommodation process
