IES Grant

Title: Enhanced Value-Added Models for Estimating Teacher Effects
Center: NCER Year: 2004
Principal Investigator: Lockwood, J. R. Awardee: RAND Corporation
Program: Statistical and Research Methodology in Education      [Program Details]
Award Period: 3 years Award Amount: $500,000
Type: Methodological Innovation Award Number: R305U040005

Purpose: This research examined the performance of a class of value-added models for longitudinal student achievement data where we introduce and use latent student parameters to enrich other features of the model.

Project Activities: The two primary model enrichments (1) allowed teacher effects to depend on the latent student parameters, and (2) allowed the probability of students missing testing to depend on the latent student parameters.
