The State of the State in Reading
Barbara Foorman, Ph.D.Yaacov Petscher, Ph.D.
Florida State University Florida Center for Reading Research
Closing the Achievement Gap• Has been the focus of the federal initiative in
education since ESEA passed in 1965.• Controlling for SES (FRL, minority, ELL
status) in analyzing for achievement gains is widespread. Ex: Beat the Odds analyses.
• With NCLB passage in 2001 and emphasis on AYP, value-added analyses popular.
• Debates regarding growth vs. attainment and definitions of proficiency continue.
Outcome Measures
• Percent meeting high standards in reading: % students passing FCAT (FCAT SSS)
• Percent making reading gains: % students making one year’s worth of growth (FCAT DSS)
• Percent of lowest 25% making reading gains: % students in lowest quartile that made 1 year of growth (FCAT DSS

Comparison of Methods
• Covariate Adjusted Scores– Demographics – Academic achievement
• Latent Class Analysis– Demographics – Academic achievement

FLDOE Method
• Sort your data file• Calculate mismatches• Identify schools that meet some criteria
– What schools are consistently in the same group over all three dependent variables?
Number of Identified Schools
Different Approach
• Policy analyses are fun but…..• Do schools tend to cluster?• Can we describe profiles in a meaningful
way?• Are profiles similar to BTO groupings?• What are the differences in identification?
Evaluating Fit
• Traditional LCA– AIC– BIC– Boostrap Likelihood Ratio Test– Entropy
• Posterior Probability– Used a conservative estimate of 0.80
• Elementary – 14 schools dropped• Middle – 8 schools dropped• High – 5 schools dropped

Comparing the Classification
What Can We Do?
• Describe the clusters• Explain the differences• Provide better recommendations to
stakeholders• Benefits of LCA
– Reduced measurement error– Include all schools– Multivariate
