Eisner's connoisseurship model is an approach to curriculum evaluation that emphasizes qualitative appreciation. It focuses on getting details of what happens in the classroom through knowledgeable evaluation. The model believes an expert evaluator can determine a curriculum's success using skills and experience in combination with appreciation and criticism. Criticism in this context refers to saying useful things about complex topics to help others see what they may have missed before. An eclectic approach to evaluation develops criteria to assess models sensitively while considering client concerns and unintended effects. It gives homeschooling parents control but some worry children may not learn enough or at the right time for testing.
