Arbiter is a K–12 athletics and activities management platform that helps schools, districts, state associations, and officials manage the administrative operations of scholastic sports and extracurricular programs. The platform connects registration, scheduling, payments, facilities coordination, eligibility tracking, officiating management, and compliance oversight in a single system, reducing the need for separate tools and manual data entry across departments. Arbiter is used by athletic directors, school administrators, state association staff, assigners, officials, coaches, and families. It supports programs ranging from individual schools managing a single sport to state associations overseeing compliance and eligibility across hundreds of member institutions. Key features and capabilities include: Registration & Eligibility — Digital student registration with customizable forms, electronic signatures, payment collection, eligibility verification, and injury management tracking for athletic and non-athletic activities. Game & Event Scheduling — Centralized scheduling for games, practices, and events across all sports and activity levels, with conflict detection, roster generation, and real-time updates synced to external calendars. Officiating & Assigning — Tools for assigners and officials to manage availability, assignments, certifications, background checks, and communication through a shared interface. Payments — Integrated payment processing for officials, event workers, and participant fees, including automated 1099 generation and multi-method payment support for associations and schools. Facilities Management — Scheduling and rental workflows for school and community facilities, including reservation requests, approvals, and invoicing. Compliance & Oversight (Arbiter 360) — A state association platform for managing eligibility, student transfers, Title IX reporting, and rule enforcement across member schools. Websites & Communication — Automated athletic websites that publish schedules and scores in real time, alongside traceable messaging tools for administrators, coaches, and families. Arbiter integrates with student information systems (SIS), financial software, and single sign-on (SSO) tools to support district-level consistency. The platform is the official and exclusive event, game, and team scheduling partner of the National Federation of State High School Associations (NFHS).
