Mississippi is seeking a qualified vendor to provide a comprehensive formative and summative assessment platform for K-8 and high school students. The platform will support the development and administration of assessments in English Language Arts, mathematics, and science, as well as high school subject areas covered by state testing requirements.

The selected solution must feature robust, standards-aligned scoring capabilities for constructed response and writing prompt items. The platform should incorporate automated or AI-supported scoring technologies that uphold the rigor, reliability, and validity standards set by high-stakes, standardized assessments. It is essential that the scoring engine is trained on grade-level standards, utilizes agency-approved rubrics, and meets benchmark performance expectations, while ensuring bias mitigation in line with human-scored environments. Transparent scoring criteria with detailed, trait-level feedback, and options for human review and override are required for effective quality assurance.

Additionally, the vendor will be responsible for delivering a customized professional development plan, which includes training timelines for agency principals, technical onboarding, online, job-embedded resources, and accessible support channels. The system must ensure testing security, support for special populations, and provide user-friendly, secure online reporting designed to enhance classroom instruction.
