<p>There is another type of "teaching to the test." Successful teaching relies on evaluation, not just of students, but of the instruction itself. In this process the teacher decides on the outcomes he or she would like to see from the students. Then an evaluation is designed to determine if indeed those outcomes have been achieved. Next, the starting point of the instruction is determined by describing the skills or knowledge that will be required prior to instruction or the skills or knowledge the learners have, and then the instruction is designed that will take the students from their entering repertoire to the outcomes identified as measured by the evaluation instrument. If students are not successful, the instruction is adjusted until it produces successful students. Careful iteration of this process of adjusting the teaching methods until the measured outcomes are reached can ensure that almost all children reach the desired outcome.</p>
