Culture is great, students are awesome.
It is unclear how people are hired (likely nepotism, or who wins the HR lottery). HR sends out a resume (whenever/if ever they feel like it), and great educators can be stuck as a sub for 5+ years. If you want to know why teacher attrition is so high, then stop keeping people trapped in poverty substitute wages for years. At some point people give up, stuck in a poverty rut.
I would not recommend this job to my past self. Teacher training programs keep pumping out the graduates. Strongly recommend to avoid EPSB and this profession, in general.
