Step One: The value-added scores also fluctuate between years. A teacher who gets a particular ranking in year one is likely to get a different ranking the next year.
Step Two: The added value of a teacher’s score fluctuates from year to year. This is why a teacher usually receives varying scores from year to year.
Step Three: From year to year, many teachers’ rankings fluctuate greatly (Ravitch, 270-271).
Step Four: A common trend seems to emerge when comparing teacher standings from year to year. That is, the grave extent to its inconsistency (Ravitch, 270-271).
Step Five: A common trend seems to emerge when comparing teacher standings from year to year. That is, the grave extent to its inconsistency. Diane Ravitch describes this pattern in her novel The Death and Life of the Great American School System by explaining how the “value-added scores also fluctuate between years. A teacher who gets a particular ranking in year one is likely to get a different ranking the next year” (Ravitch, 270-271).

You clearly grasp the key concepts. But avoid referring to Ravitch’s book as a “novel,” since that word is reserved for fiction.
