AdminPlus SIS - 2026 Pricing, Features, Reviews & Alternatives

Rediker Software delivers an integrated K-12 school management platform designed to simplify administration, improve communication, and support student success. Trusted by schools around the world for more than 40 years, Rediker connects school offices, teachers, parents, and students through a unified technology ecosystem.

At the core of the platform is AdminPlus®, a comprehensive Student Information System (SIS) that serves as the central source of truth for student, parent, staff, and school data. Schools use AdminPlus to manage enrollment, attendance, scheduling, discipline, report cards, transcripts, health records, communications, and reporting within a single secure solution. Powerful dashboards, flexible reporting tools, and real-time access to data help administrators make informed decisions while reducing administrative workload.

Integrated with the SIS is TeacherPlus Gradebook, a robust online gradebook that enables teachers to manage grades, assignments, attendance, assessments, standards-based learning, and classroom reporting efficiently. Because TeacherPlus and AdminPlus share the same database, information is synchronized automatically, eliminating duplicate data entry and giving school leaders complete visibility into academic performance.

PlusPortals® strengthens school-to-home communication by providing secure online access for parents and students. Families can view grades, assignments, attendance records, schedules, report cards, transcripts, announcements, and other important school information anytime through web and mobile devices. Real-time access helps increase engagement, improve transparency, and foster stronger partnerships between schools and families.

Rediker's integrated Tuition Management and Student Billing tools help schools streamline financial operations while delivering a convenient experience for families. Schools can manage tuition plans, billing, online payments, account balances, incidental charges, automated payment schedules, and financial reporting within the same platform used to manage student information. By connecting financial data directly to student records, schools gain greater efficiency, improved accuracy, and better visibility into account activity.

Designed specifically for K-12 education, Rediker's platform brings student management, classroom performance, family engagement, and financial administration together in one connected system. The result is less time spent managing software and more time focused on supporting students, families, and educational outcomes.
