This growth model work group will help study and make recommendations for a research-based growth to be used as part of South Dakota’s new accountability system. Beginning with the 2014-15 school year, the new system will include academic growth as one of the three indicators that make up the School Performance Index at the elementary and middle school levels.
• The Gain Score growth model describes growth with simple differences of average gains over time.
• The Residual Gain model describes growth as the difference between current status and expected status given past scores.
• The Trajectory model extends gains or average gains in a predictable, usually linear fashion into the future.
• The Categorical model defines growth by transitions among status categories (i.e. Basic, Proficient, Advanced) over time.
• The Projection model uses past scores to predict future scores through regression equations.
• The Student Growth Percentiles model employs a percentile rank of current status in a reference group of students with similar past scores.
• The Multivariate or Value Added model uses entire student score histories, including other subjects and teachers, to direct higher than expected student scores associated with particular teachers.
