what are the disadvantages of informal research
One of the most significant disadvantages in using informal reading assessments is the lack of validity and reliability data. Validity means that an assessment tests what it is purports to test. [ [ For example, a test of third-grade reading should not be written for a seventh-grade level. Reliability refers to an assessment that elicits consistent results; the same test will offer the same results repeatedly. Informal assessments do not lend themselves to being tested for validity and reliability. Therefore, students' scores cannot be easily compared to their previous scores, scores of
other students or to a particular criterion. ]
