  1. Agenda • Student Learning Growth • Teacher VAM • School Growth • PYG • Area Scorecards. PYG, and other Performance Indicators

  2. Florida Department of Education’s “Value-Added Model (VAM)” Marc Baron, Chief, Performance Accountability Mark Howard, Director, Research, Evaluation, and Assessment

  3. FLDOE Value-Added ModelEstablished by Student Success Act (SB 736) • Evaluation Criteria for All Instructional Personnel and School Administrators • Professional Practice • Student Learning Growth • FCAT Classroom Teachers: 40%-50% • Non FCAT Classroom Teachers: 30%-40% • Non Classroom Teachers: 20%-30% • Principals: 50% • JTEC & Principal Evaluation Committee

  4. SDPBC Must Classify Instructional Personnel and School Administratorsinto these Four Categories • Highly Effective • Effective • Needs Improvement • Unsatisfactory

  5. VAM & Student Learning Growth • Contribution to a change in a student’s achievement • Calculated from a measure of student learning growth

  6. What is the Student Learning Growth Score? The difference between Current test score and Predicted test score What is the Predicted Student Score?

  7. What is the Predicted Student Score? It is score you would predict a student to achieve based on the student’s performance on prior tests and other information available on the student

  8. FLDOE Value-Added ModelVariables determining student learning growth • Two or more years of prior achievement scores • Gifted status • Student Attendance (Days) • 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

  9. FLDOE Value-Added ModelVariables determining student learning growth • Students with Disabilities (SWD) status • Language impaired • Hearing impaired • Visually impaired • Emotional/behavioral • Specific learning disability • Dual sensory impaired • Autism spectrum disorder • Traumatic brain injury • Other health impaired • Intellectual disability • English Language Learner (ELL) status • LY

  39. What is a Teacher Value-Added Score? and How is it calculated? DRE

  40. FLDOE Teacher Value-Added Score Conceptual Teacher Effect ) ( ) ( - + .5 X = School Growth Score School Growth Score Teacher Growth Score Tchvas = (Tchgrowth score – Schgrowth score ) + ( .5 x Schgrowth score) DRE

  41. Teacher Value-Added Score Tchvas = (Tchgrowth score – Schgrowth score ) + ( .5 x Schgrowth score) DRE

  42. State Average Student Learning Growth Teacher Growth = 20 The greater a teacher’s growth score is from the state’s average and the school’s growth score, the higher a teacher’s VAS VAS = 15 VAS = 20 VAS = 25 -20 -15 -10 -5 0 5 10 15 20 Tchvas = (Tchgrowth - Schgrowth ) + ( .5 x Schgrowth)

  43. State Average Student Learning Growth Schoo l Growth = 0 At a school with a growth score of 0, the teacher’s VAS equals the teacher’s growth VAS = 20 VAS = 0 VAS = -20 -20 -15 -10 -5 0 5 10 15 20 Tchvas = (Tchgrowth - Schgrowth ) + ( .5 x Schgrowth)

  44. State Average Student Learning Growth Schoo l Growth = 10 What is the significance of the green line? At a high VAS school, a teacher’s growth must exceed half the school’s growth to have a positive VAS VAS = 15 VAS = 5 VAS = 0 VAS = -5 VAS = -10 -20 -15 -10 -5 0 5 10 15 20 Tchvas = (Tchgrowth - Schgrowth ) + ( .5 x Schgrowth)

  45. State Average Student Learning Growth Schoo l Growth = -10 At a low VAS school, a teacher’s growth must exceed half the school’s growth to have a positive VAS VAS = -15 VAS = -5 VAS =0 VAS = 5 VAS = 10 -20 -15 -10 -5 0 5 10 15 20 Tchvas = (Tchgrowth - Schgrowth ) + ( .5 x Schgrowth)
