The My Sub K-12 app for substitutes is part of Tyler Technologies’ Absence & Substitute software, powered by ReadySub. This free app empowers substitutes to review job openings, receive job notifications, and retrieve lesson plans. Available jobs are posted by districts using the Absence & Substitute software, and notifications are sent to substitutes who work in that district.With the free My Sub K-12 app, substitutes seeking part-time or temporary K-12 employment will be able to access jobs by location, job type, and classroom. They can also view their past jobs and account information right from the mobile app.For support questions, access live chat, phone, and email support from tylertech.com. As My Sub K-12 relies on accurate information from your school district, please contact your district leadership directly if you have additional questions or concerns about posted openings.
