The WV Growth Model: Our Purpose • To provide an answer to a few common questions: • “How much did my student grow this year?” • “What does this growth mean compared to everyone else?” • “Is it enough growth?” What do these three questions have in common? Information about students
Status vs. Growth • Before growth, let’s review terms • Status: A snapshot measure of a single point in time – “Proficiency” • Growth: Multiple snapshots across many points in time
Measuring Growth: A Primer • Uses all available data to answer three questions: • Am I proficient? • How much did I grow? • Is it enough growth? • The WV Growth Model yields: • Student Growth Percentiles (SGPs) • What are SGPs? • How much did students grow compared to everyone else? • Think height and rate of growth
What is a Student Growth Percentile? • Given (3 things): • A student’s prior scale scores • Academically similar students • Current scale score • A student’s current scale score represents a percentile of growth – a Student Growth Percentile • Think of it as the probability of a student’s current achievement based on their past achievement: • Pr(Current Achievement|Past Achievement) • Growth percentiles describe the probability/rarity of a student’s current achievement based upon their prior achievement.
Measuring Growth: A Primer • What is the likelihood of current (and future) performance given past performance? • Based on students who have similar academic histories (academic cohort) • Uses all available data to answer those three prior questions: • Am I proficient? (Status) • How much did I grow? (SGPs) • Is it enough growth? (Growth to Standard)
Our Growth Options (Primer, cont’d) • How much growth? – Starts with the student. Can be aggregated to drive school conversations • Low Growth (bad surprises) • Typical Growth (a statistical expectation) • High Growth (good surprises) • Is it enough growth? – Can drive studentlearning conversations • Catching Up • Keeping Up • Falling Behind
Why do we care? • Why growth? 4 Driving Questions • How much growth did my student exhibit? • What does this growth mean? • How much growth does my student need to be proficient in the future? • How likely is this growth? • Student Reports – the primary benefit of the WV Growth Model
