Identifying Emergent Bilinguals with the LAS Battery of Assessments

Best Practice: Connecting Identification Data to Instruction
Going beyond compliance/LPAC and providing teachers with the preLAS and LAS Links data collected at the point of Emergent Bilingual identification, equips teachers with not only knowing the grows and glows of each student, but it allows them to immediately make data driven instructional decisions. The following resources will:

  • Help your teachers to gain a better understanding of the preLAS and LAS Links data generated during the identification process
  • Connect the identification data to strategies that your teachers can immediately implement in the classroom
  • Provide your teachers, students and parents with resources and activities that will promote student language growth…at no additional cost!
