Thank you for your attention.

FLDOE Value-Added Model

• Teacher Component

• School Component

• Based on Student Learning Growth– Predictions cannot be different based on student’s

gender, race, ethnicity, or socioeconomic status

FLDOE Value-Added Model Variables determining student learning growth• Two or more years of prior achievement scores • Gifted status • Attendance • Mobility (number of transitions) • Difference from modal age in grade (indicator of retention) • Class size • The number of subject-relevant courses in which

the student is enrolled• Homogeneity of entering test scores in the class
