Roster Verification


Teacher value-added data is used for a number of diagnostic and evaluative purposes, including teacher evaluations. The roster verification process plays a crucial role in ensuring that there is accurate data for calculating teacher value-added reports and evaluation composites. Shortly before the launch of fall and spring state testing, teachers use the roster verification (RV) process to roster students they taught during the school year. Once teachers have completed and approved their rosters, the rosters are used in calculating teacher value-added scores (TVAAS).


Additional Guidance

  • In order to be included in TVAAS calculations and to ensure reliable data to assess growth, students must have sufficient prior testing history (three prior assessments).
  • Subject-specific components of a state assessment count as separate tests.
  • Only students that have a three-year prior testing history are included in growth calculations.
  • More information about TVAAS can be found here.
  • Students that are rostered by a teacher but are labeled as part-time during the linkage process due to insufficient instructional days are not included in the individual growth score calculation.
  • For the EOC: Teachers must roster at least 10 separate students with testing history who add up to 6 full-time equivalent students to earn an individual growth score.
  • For TCAP: Teachers must roster at least 6 full-time equivalent students to earn an individual growth score.
