Hello, in response to your question. You have to apply and take a written and practical exam to be considered for the EMS academy. Once hired you attend an academy based on BLS care. Once you pass the academy, to include a preceptor evaluation period, you are used as coverage personnel for your first year (meaning what ever shift needs to be filled you fill) after that you may bid on a perm shift/ambulance. After you have been in the union for a year you are allowed to take the exam to be considered for acceptance into the paramedic academy. After being accepted you have to retake paramedic school, and then you may or may not be selected to work as a paramedic for Boston EMS. I hope this answers your question. As to the residency requirement, yes you have to live in the city of Boston to work for Boston EMS.
