Send in your position promotion requests here. Making a request does not guarantee a promotion. Eyewire HQ will promote you based on accuracy, Eyewire activity, and community participation. Read the full requirements here: https://blog.eyewire.org/player-progression/
Promotion decisions are usually made on the last Thursday of the month, and promotions are then granted on the last Friday. For exact dates, please check your in-game notifications or the Eyewire blog.
