A comparison of NCLB Accountability Models: What schools are being identified? Jessica Allen University of Colorado, Boulder Jennifer L. Dunn Measured Progress
NCLB Growth Pilot Program Traditional NCLB Status Improvement Growth Model Pilot Growth towards proficiency Schools need to meet one of these models to make Adequate Yearly Progress (AYP)
Growth Model Years to Proficiency Final Grade Included in Model Growth Target Calculation Target Classification AK 410 Standardized Scale Projection with correction for test reliability Observed Score AR Grade Dependent 8 Vertical Scale ProjectionObserved Score AZ 38 Vertical Scale RegressionPredicted Score (Lower Bound) FL 310 Vertical Scale ProjectionObserved Score NC 39 Standardized Scale Projection Observed Score IA Initial Score Dependent N/A Value TableObserved Score DE N/A Value TableObserved Score OH 3/next schoolN/A Multilevel modelProjected Score TN 3/graduation12 Multilevel modelProjected Score
Research Questions What is the relationship between the numbers of schools classified as meeting AYP under different pilot growth models? What is the relationship between the numbers of schools classified as meeting AYP under the status model and the pilot growth models? How does a status confidence interval influence the above decision? What is the relationship between the numbers of schools classified as meeting AYP under the improvement model and the pilot growth models?
Methods All models applied to single data set. Two years of data from vertically scaled state math assessment. Models applied [3 Cut points] Low (58%), Med(72%), High (80%) Status [Percent Proficient or Above] CI [95%, 98% 99%] Improvement [Safe Harbor] Growth [AK, AR, AZ, DE, FL, IA and NC]

Conclusions Status, Improvement and Growth to Proficiency are different constructs However there is overlap in schools meeting each standard. A handful of different schools are meeting the Growth to Proficiency but not Status and Improvement. Unclear if these are “growing” schools or schools near status cut.
Future Research Can growth model differences be explained by model characteristics? Are the models defined appropriately? Are growth targets realistic and obtainable? What is meant by growth to proficiency?
