About

DSS Drive & Teach

Features
Read full description

DSS Staff Portal is the official mobile companion for Driving School Software (DSS) — a commercial SaaS platform used by more than 850 independent driving schools and over 10,000+ instructors, office staff, and administrators across the United States. DSS is not an app for one company or one driving school. It is a multi-tenant platform: each school is a separate, independently owned business that licenses DSS on its own. Instructors and staff use personal devices, often work at one school, and sign in with credentials issued by whichever school employs them. New driving schools subscribe to DSS at drivingschoolsoftware.com; staff accounts are created and managed through each school’s DSS web portal. This app does not include account registration — it is the mobile client for professionals who already have access through their school. Whether you are in the office or on the road, DSS Staff Portal gives you secure, real-time access to the schedules, student information, lesson tools, and evaluations you need to run day-to-day operations. KEY FEATURES Schedule Management • View daily, weekly, and upcoming lesson schedules • Stay informed about schedule changes and updates • Access instructor and student appointments • Receive notifications for upcoming lessons Student Management • View student profiles and enrollment details • Access lesson history and progress • Review training status and important notes • Quickly search for students Lesson & Evaluation Management • View assigned driving lessons • Complete in-car and classroom evaluations • Record lesson-related information and signatures • Track lesson completion and update status in real time Attendance & Activity Tracking • Record attendance for scheduled lessons • Monitor daily activities • Keep records updated instantly Communication • Stay connected with office staff and instructors • Receive important announcements and notifications • Access communication history where available Secure Access • Secure phone-based authentication • Role-based access to protect sensitive information • Data synchronization with the DSS platform Real-Time Updates • Instantly access the latest schedules, student records, and operational information • Changes made in DSS are reflected in the app to help staff stay current throughout the day WHO IS THIS APP FOR?
