Accountability Update: Top-to-Bottom Alexander Schwarz Office of Psychometrics, Accountability, Research and Evaluation Michigan Department of Education
Top-to-Bottom(TTB) List Used as measure of accountability U.S. Department of Education Schools ranked from 99 to 0 on student performance Schools held accountable: • Achievement • Improvement • Achievement Gap • Graduation (high schools only)
Top-to-Bottom Ranking Reward: highest performing, greatest progress, Beating-the-Odds (BTO) schools Focus: largest achievement gaps Priority: lowest performing schools
Top-to-Bottom Changes in 2013 • Highest four, five, or six year graduation rate used • z-score values are capped to -2 and +2 • Scorecard performance impacts Top-To-Bottom Priority and Focus categories
Components of TTB Each component applies to each subject for a school: • Achievement • Improvement in achievement over time • Achievement gap measure between top scoring 30% of students versus the bottom scoring 30% of students Individual components tell schools something about their overall performance and can be used for diagnostic purposes
Which schools receive a ranking? Schools with 30 or more full academic year (FAY) students in the two most recent years in at least two state-tested content areas Some schools do not receive a ranking if they: • Have too few FAY students • Only have one year of data • Have a grade span that does not include two tested areas
Grade Span Difference • For Mathematics and Reading in grades 3-8, testing every year allows us to calculate improvement in achievement based upon individual student performance level change • All other subjects and grades use a slope calculation based upon cohorts of students
What about reconfigured Schools? • A school must change by four or more grades in order to get a new code • Example: A K-2 building becoming a K-6 building • New codes are NOT granted when a school is reopened as a charter, for example • If not, the school retains the old code and continues to have data “point” to it from all students for whom that code is their feeder school
Why do we use z-scores? • z-scores are a standardized measure that help compare individual student (or school) data to the state average data (average scores across populations) • z-scores “level the playing field” across grade levels and subjects • Each z-score corresponds to a value in a normal distribution. A z-score will describe how much a value deviates from the mean • z-scores are used throughout the ranking to compare a school’s value on a certain component to the average value across all schools
z-Score “Cheat Sheet” Student z-score = (Student Scale Score) – (Statewide average of scale scores) Standard Deviation of Scale Score School z-score= (School Value) – (Statewide average of that value) Standard deviation of that value z-score Summary PowerPoint and Business Rules- http://www.michigan.gov/mde/0,4615,7-140-37818_56562---,00.html
Modifications to 2012-2013 Top-to-Bottom • Based upon feedback from the field • Concern with outliers having an inordinate impact on the identification of focus schools • Modified all student level scores • Normalize all student z-score distributions • Cap all student z-score distributions at -2 on the lower end and at +2 on the upper end
2012-2013 Focus School Status • Prohibit from appearing on the focus list any schools as defined by both of the following: • The school’s bottom 30% group proficiency rate is higher than the state average proficiency rate in at least two subject areas • The school’s top to bottom percentile rank is at least 75
Good-Getting-Great • Applied in 2012-2013 Accountability Cycle • Prohibit from appearing on the focus list any schools as defined by both of the following: • The school’s bottom 30% group meets the safe-harbor requirement in all applicable subject areas as determined in the Accountability Scorecard • The school’s top to bottom percentile rank is at least 75
Overview of Ranking Results • 2798 Schools ranked • 137 Priority Schools • 52 new schools • 85 first designated as Priority in previous cohorts • 349 Focus Schools • 342 Reward Schools
Characteristics of Priority Schools • High schools not more likely to be Priority Schools • E/MS schools make up a higher proportion now • Percent of students in school who are LEP no strong relationship with Priority Status • Percent of students SWD related to Priority Status (as % SWD increases, so does number of Priority Schools) • Very strongly related to economic disadvantage • 73% of our Priority Schools in the 2013 cohort are high economic disadvantage (over 75% of students ED) compared with 18% of the state • Also strong relationship between % minority students and Priority status; not as strong as ED • Urban schools overrepresented; rural schools underrepresented
Characteristics of Focus Schools • 185 schools were Focus in 2012 and 2013 • 164 are new to Focus in 2013 • 173 came off the list • 8 became Priority • 125 have no label • 37 are Reward • 3 are not ranked
Focus 2013 relative Focus 2012 More schoolwide Title I schools identified More rural schools, fewer urban schools, more small and large schools, fewer 400-800 student schools Fewer low ED schools, more 50-75% ED schools
