Built for Every Role
From students taking assessments to district leaders making data-driven decisions — MOSAIC serves every stakeholder in the ELL ecosystem.
WIDA-Aligned K-12 Assessments
Full exam coverage across all 4 language domains — Listening, Speaking, Reading, and Writing. Students take grade-appropriate assessments with built-in audio, image scaffolds, and can pause and resume at any time.
Classroom-Ready Print Booklets
The only commercially available printed practice assessment that replicates the exact WIDA ACCESS paper format — Part A/B/C thematic groupings, STOP signs between sections, Tier A and Tier B/C separate booklets. Each grade pack includes 20 Student Test Booklets and 1 Teacher Edition with WIDA level mapping, answer keys, and Scoring Worksheets.
431 Hand-Crafted K-2 Pictograms
Emerging readers in Kindergarten through Grade 2 answer questions using visual pictogram illustrations instead of text-only choices. Every answer option has a unique, purpose-built image so students can demonstrate content knowledge without a reading barrier — a feature no other assessment product provides at any scale.
AI Rubric Scoring with GPT-4o
Speaking and Writing responses are evaluated by GPT-4o against WIDA rubric dimensions — Linguistic Complexity, Vocabulary Usage, and Language Control for Speaking; plus Organization for Writing. Teachers see AI-suggested scores with dimensional breakdowns, but always retain final scoring authority.
Smart Grading with Student Context
Teachers instantly see which student, class, and school each response belongs to. Score Writing and Speaking responses using WIDA rubrics (0-6), add personalized feedback, and track class performance across assessment windows.
District-Wide School Performance
Rank and compare every school in your district. See which schools are Exceeding, Meeting, Approaching, or Need Support. Drill down into domain scores, WIDA distributions, grade-level gaps, and growth trends.
Per-Modality Adaptive Difficulty
MOSAIC adjusts question difficulty independently for each modality based on the student's historical performance. A student strong in Reading but developing in Writing gets appropriately challenging content in both — automatically.
Role-Based Access Control
Students only see their enrolled grade and never access answer keys, teacher resources, or results data. Strict RBAC ensures every user sees exactly what they should — nothing more.
Predictive End-of-Year Projections
Using linear growth trajectory analysis, MOSAIC projects where each student will be by the end of the school year. Students are classified as On Track, At Risk, or Needs Intervention — giving teachers months of lead time to adjust instruction.
Cohort Comparison & Gap Detection
Compare modality performance across grades, schools, or classrooms with bar charts, heatmaps, and data tables. Automatic systemic gap alerts flag when any modality falls below the cross-cohort average — turning data into actionable PD decisions.
ERMA/FERPA Compliance Suite
Purpose-built for NYCPS procurement review. Configurable data retention, COPPA consent for K-5, breach incident logging, FERPA-compliant parent data export, and complete student data deletion — with a pre-built DPA template ready for signing.
Platform Highlights
Print & Digital Modes
Students can take exams digitally or use professionally printed booklets that replicate the exact WIDA ACCESS paper format — including Tier A and Tier B/C separate booklets.
AI Rubric Scoring
GPT-4o evaluates Speaking and Writing responses against 3-4 WIDA rubric dimensions. Teachers see AI-suggested scores with full dimensional breakdowns but always retain final authority.
Growth Tracking
Longitudinal data across Fall, Winter, and Spring assessment windows shows exactly how students progress across all four modalities.
District Analytics
Compare schools by WIDA score, modality, and grade. Instantly see which schools need support and where resources should go.
Strict Security
Students only access their enrolled grade. Answer keys, teacher resources, and admin data are completely hidden.
Multi-Tenancy
Full hierarchy support: Districts, Schools, Classes, and Students. Each level has its own dashboard and permissions.
STT & TTS
Built-in speech-to-text and text-to-speech for the Listening and Speaking modalities. AI-powered evaluation.
ELD Standards & KLUs
Every question mapped to WIDA's 5 ELD Standards and 4 Key Language Uses — enabling standards-based reporting and instructional alignment.
Can-Do Descriptors
Embedded Can-Do Descriptors show what students CAN do at each level with growth targets for the next level.
