Well as an employee of one of the districts interviewed with an opening still, who has been in the district longer than the average an lives in my village year round I have a few ideas of how to up our teacher retention :
1) bring back our district inservice trainings that have been canceled the last two years, nothing like being asked to teach a new curriculum with the only training you have received being a spotty video conference, then being harshly reviewed on it a week later.   2) promote living year round in the village. Stop having it be a place people come to work and then leave as soon as there is a break.  3) fix the physical problems with our housing and school buildings.  One of my coworkers hasn't had working plumbing for over 8 months and no work on it all summer.  4) stop hiring people who have a short term mindset.  It's crazy how many hires I heard this year say I'm up here to cross a bucket list iteam (but please keep up welcoming them in anchorage as this helps them)
