Parents, if your school uses School Dismissal Manager (SDM), this app lets you schedule your child's school dismissal instructions for any day within the next two weeks. Your child's typical everyday instruction is already set, so only exceptions need to be entered. Pick from your school's dismissal options and add a note if needed. Notify your school of your wishes in just a few seconds. Get a reminder on days your child has a dismissal exception. Your school will supply you with new login credentials at the start of the school year. Login, set your own password, then SDM is always only a click away. If your school uses SDM's FastLane for car line management, you can check in from the car line driveway. Your check in calls your children from their classrooms and lets the car line admin know you have arrived. This makes your school's car line faster, easier, and safer for your children. This app only works for parents in schools that use School Dismissal Manager (SDM) to streamline their dismissal process.

I can’t even see the password I entered to confirm that it’s correct. The same password works on desktop but is rejected in app. Have you even tested with a password manager? ### 1/5 — Error! Invalid Login *2025-08-20, version 11.00.22* The app doesn’t work anymore. The website works, but the app just returns Error! invalid login. But it’s the same login that works in the website!?!?!??!? Painful user experience. ### 1/5 — Can’t log in *2025-08-20* Well this app is useless. I can’t even see the password I entered to confirm that it’s correct. Have you even tested with a password manager? ### 2/5 — Glitchy *2025-08-20, version 11.00.22* Doesn’t let you edit exceptions when needed ### 2/5 — Error *2025-03-25, version 10.18.30* If I leave the app open after the last time using it then I get an error message and have to close and reopen the app. ### 1/5 — Stopped sending changes *2025-02-21, version 10.17.30* I made an exception for the day for my children and it did not show up on the school end I had no issues till this week where is suddenly did not report my changes ### 1/5 — Buttons in app don’t even work *2025-02-06, version 10.17.30* How this was sold to schools and how it is still broken is beyond me. Can’t submit an exception because the buttons on that page are all broken. “Add Exception” “cancel” and “Back to Calendar” buttons do not work on the add exception page. It’s been this way for at least months and remains unfixed. ### 2/5 — 3 Days into using as a parent and already annoyed at the UI and UX issues *2024-08-28, version 10.15.30* The constant, repeated (sometimes as many as 10) “your session has timed out” prompts that pop up when you open the app is enough to get you started on a bad foot. When another parent creates an exception for you to pick up their child, it does not show up in the “Today’s dismissal” section and only lets you know the other parent did what they need to do correctly once you check-in. If I want to know before hand, I just have to pray that everything is right and whatever god you believe in has it right - cause you sure won’t be able to tell it’s right in the app. Overall, there are multiple confusing sections and options in the parent app which should be pretty simple. SDM needs to work on cleaning up their options and presenting them to the end user better. ### 1/5 — Doesn’t work *2024-08-20, version 10.12.30* Won’t let me create an account Update: the school hasn’t been able to give me any information as to why the app is not work and has said I’m not the only one having issues ## Frequently asked questions about School Dismissal Manager (SDM) ### What does the School Dismissal Manager (SDM) app do?
