AERA March 25, 2008 Delaware’s Growth Model and Results from Year One

Background Information Invitation for states to submit proposals to use a growth model Pilot project – up to ten states Model must demonstrate that it can raise student achievement and enhance school accountability “Bright Line” principles of NCLB upheld DE first submitted proposal in March 2006 – was denied DE revised/resubmitted proposal September 2006 USED approved for use in with one condition –Cannot use Confidence Interval Calculate AYP by original and growth models Report both original and growth models

Why did we submit? To ensure more valid and reliable accountability determinations To monitor various subgroups progress To support our value of continuous improvement and longitudinal student growth

What model did we propose? Value Table Model –Maintains emphasis on performance levels (standards based achievement) –Values longitudinal student growth –Gives schools credit for moving students towards proficiency –Values growth especially below the standard

Who chose Delaware’s model? Committee of Stakeholders –District administrators, school administrators, teachers, parents, community

How do value tables work? Values are placed in a table to indicate points earned from one year to the next Calculate the average growth value for the school and each subgroup in reading and math Compare average growth to the target

Delaware’s Accountability System: Adequate Yearly Progress (AYP) 2006 Participation (ELA, Math) Performance (ELA, Math) –Total School Original Status / Safe Harbor –Subgroup Original Status / Safe Harbor Other Academic Indicators 2007 Participation (ELA, Math) Performance (ELA, Math) –Total School and Subgroup Growth Original Status / Safe Harbor Other Academic Indicators

How to meet AYP Meet Growth Value Targets or Original Status Targets in ELA and math Meet Participation Targets in ELA and math Meet the Other Academic Indicator

Ratings Ratings are determined by the combination of: AYP Determination State Progress Determination Accountability History

What Happened in 2007? 193 Schools with ratings –146 schools (76%) used growth model for rating 89 schools (46%) used growth model and made AYP 57 schools (30%) used growth model and did not make AYP –47 schools (24%) used original model for rating (all made AYP)

Comparison of Growth to Original 82 schools (42%) made both growth and original 57 schools (30%) did not make growth or original 7 schools (4%) made growth but not original 41 schools (21%) made original but not growth 6 schools used original model only – K, K-1, K-2 schools – no growth available

Correlation of Growth and Original Models – A look at those schools that did not make AYP (57 schools) Missed reading in growth model also missed reading in original model for same subgroups Missed math in growth model may or may not have missed math in original model for same subgroups Missed special education in reading or math in growth model also missed in original model

Some Observations Growth model results will be similar to Original –Principles of NCLB, 100% proficient by –Different models produced similar determinations Growth models only help when real growth is occurring –Showing growth in low achieving students but rate of improvement is differs by subgroups If AYP was not met: –½ of the students maintained their level from previous year –1 in 4 improved –1 in 4 regressed –Similar pattern across subgroups
