I student taught in Holyoke, MA, spent 3 years in Lawrence, MA and worked seven years and one semester in Salem, MA. These are all urban, high needs districts. Salem is a diverse community. We have immigrants from around the world, keep nearly all of our special education students in district (which puts us at around 30% of the population on an IEP or 504), many students are bilingual, around 10% are in the ELL program and over 50% receive free or reduced lunch. As someone who grew up in an affluent suburb without much diversity I value the many perspectives that my students share and am truly impressed with how respectful students are of all their peers.

The GSA has a small core of students who meet weekly. Those students plan events for the larger community who are supportive but may not be able to attend regular meetings. These events include Day of Silence, Coming Out Day and Ally Week.
