Mr. Penderfield is a special education coteacher in an American Literature class. The ability level of the class is quite diverse. There is a mixture of special education, regular education, and gifted education students in the class. The regular education teacher and Mr. Penderfield are in the process of creating a tiered assessment. Their fear is that a tiered assessment that is made up of both challenging and easy to complete assignments, to meet the needs of all students, will encourage everyone to complete the easiest assignment. What can the teacher do to solve this problem?
