Step One: \u00a0No measure is perfect, but the estimates of value-added and other \u201cgrowth models,\u201d which attempt to isolate the \u201ctrue effect\u201d of an individual teacher through his or her students\u2019 test scores, are alarmingly error-prone in any given year.<\/p>\n
Step Two: \u00a0 Assessments of teachers change from year to year. \u00a0A teacher with a high ranking one year may receive a lower ranking the next year.<\/p>\n
Step Three: \u00a0The scores can change between years. \u00a0A teacher’s ranking one year is likely to receive a different ranking the next year. \u00a0There will always be changes in these rankings, and sometimes the changes will reflect actual performance changes (Ravitch, 270-271).<\/p>\n
Step Four: \u00a0It is difficult to hold teachers accountable for their students’ success because there is no easy way to assess a teacher’s progress. \u00a0This is because the current models of assessment are unreliable (Ravitch 270-271).<\/p>\n
Step Five: \u00a0\u00a0It is difficult to hold teachers accountable for their students’ success because there is no easy way to assess a teacher’s progress. \u00a0This is because the current models of assessment are unreliable. \u00a0Diane Ravitch says, “No measure is perfect, but the estimates of value-added and other ‘growth models,’ which attempt to isolate the ‘true effect’ of an individual teacher through his or her students\u2019 test scores, are alarmingly error-prone in any given year (Ravitch, 270-271).<\/p>\n","protected":false},"excerpt":{"rendered":"
