Betty Stone has been a BEST Plus (BP) trainer since 2004, when Massachusetts adopted BP to assess adult ESOL learners’ proficiency. She earned an M.A.T. in French and ESL from the SIT Graduate Institute in Vermont and spent five years teaching EFL and workplace literacy in Portugal. For 32 years she was an ESOL Program Administrator at SCALE, Somerville’s adult learning center. Recently she has been tutoring a non-literate Afghan couple in math and English. In all her roles—teacher, trainer, supervisor, and consultant—creating opportunities for rich exchange of ideas with colleagues and learners has always been Betty’s favorite professional activity.
