Tomlinson (2001) described differentiated assessment as an ongoing process through which teachers gather data before, during, and after instruction from multiple sources to identify learners’ needs and strengths. In a quality class that is built on the foundation of differentiation, the teacher will infuse a constant stream of assessments (before, during, and after) to help identify student’s needs and to help improve learning.

Instructions
 

After viewing the resources:

• Explain      the role of assessment as it applies to theoretical foundations of      differentiated instruction. 
• Describe      how assessment can be created that evaluates a student’s true knowledge      without bias towards language barriers, learning differences, or cultural      differences. 
• Choose      one differentiated assessment strategy (either pre, formative, or      summative) from the course text (or from the recommended websites or      video) and present a rationale for using the assessment to meet the needs      of diverse learners and how it will be used to drive future      instruction.
