A nationwide diagnostic analytics platform transforming billions of standardized assessment data points into intuitive, prioritized school improvement roadmaps for 500k+ schools and educational leaders.
01 / From Intimidating Data to Empathetic Guidance
Standardized national evaluations previously felt punitive: schools were publicly ranked on leaderboard tables that shamed low-performing rural schools without providing any guidance on how to improve.
Our first design decision was to eliminate comparative rankings entirely. Instead, we designed a diagnostic model inspired by clinical medicine:
• Health Diagnostic Paradigm: Schools receive a holistic assessment across three fundamental pillars: Student Competencies (Literacy/Numeracy), Learning Environment (Safety/Anti-Bullying), and Teaching Quality.
• Intuitive Color-Coded Tiers: Indicators are grouped into clear operational tiers ('Optimal', 'Functional', 'Needs Guidance', 'Urgent Intervention') rather than raw decimal percentiles.
• Strengths & Priority Improvement Areas: The dashboard immediately highlights the school's top achievements to celebrate, followed by the top two priority areas needing attention.
02 / Root-Cause Diagnostic Hierarchy
When a school discovers their 8th-grade numeracy scores are low, a principal's immediate question is: 'Why?'
We designed an interactive root-cause drill-down tree that connects output metrics to underlying input factors:
• Level 1 (Symptom): Numeracy proficiency is in the 'Needs Guidance' tier (62/100).
• Level 2 (Root Factor): Analysis reveals that students performed adequately on basic arithmetic but scored in the bottom 10th percentile on mathematical reasoning and word problems.
• Level 3 (Classroom Environment): Teacher survey correlation reveals that 74% of math educators relied exclusively on rote memorization rather than applied problem-solving exercises.
By visualizing the connective tissue between student scores and teacher practices, principals gained clarity on what specific interventions were needed.
03 / Closing the Loop: Data-to-Action Pipeline
Diagnosing a problem is useless if the user doesn't know how to resolve it. We engineered a closed-loop 'Inspirasi Benahi' (Improvement Inspiration) recommendation engine:
• Curated Curricular Links: For every identified weak spot, the system serves micro-learning modules from the National Teacher Platform (Platform Merdeka Mengajar).
• Budget Line Item Integration: Principals can click 'Add to Annual Budget Plan', which directly exports the recommended pedagogical interventions into ARKAS (the financial OS) as pre-approved budget line items.
• Community Best Practices: Showcases case studies and video reflections from peer schools in the same district who successfully improved similar scores in prior years.
04 / High-Performance Visualization at National Scale
Serving analytics across 500,000+ educational institutions required meticulous frontend engineering:
• Accessible D3 Visualizations: Custom SVG-based gauge and bar charts that maintain high-contrast legibility, keyboard focus states, and screen-reader accessible data tables.
• Sub-Second Query Latency: Paired with ClickHouse OLAP database clusters, aggregate queries over 100M+ student records render in less than 350ms.
• PDF Export Engine: Built a headless browser rendering pipeline allowing regional superintendents to generate beautifully formatted, board-ready executive summaries for municipal budget hearings with a single click.
05 / Transforming National Education Policy
The launch of Rapor Pendidikan revolutionized how the national education ecosystem approaches school improvement:
• 91% National Adoption: Within the first year, over 91% of public school principals logged in and generated their statutory annual improvement plan directly from the platform.
• Policy Alignment: Municipal education boards now base targeted grant allocations on diagnostic indicators rather than political influence.
• Measurable Student Outcomes: Targeted intervention programs initiated via the platform yielded a 4.2x increase in regional literacy workshops and a measurable 14% turnaround in school safety and anti-bullying compliance scores across target districts.
Project Scope & Approach
The Challenge
National standardized test evaluations were compiled into 200-page dense statistical PDFs filled with obscure standard deviations, z-scores, and bell curves. School principals and regional superintendents lacked the statistical training to extract actionable insights, leaving critical learning gaps and student safety deficits unaddressed year after year.
The Solution
Designed an empathetic diagnostic scorecard that translates aggregate statistics into clear performance tiers, root-cause diagnostics, and step-by-step school improvement recommendations linked directly to national teacher training resources and budget allocation tools.
The Impact
Adopted by over 91% of school principals across all 38 provinces as the official basis for annual school planning, sparking measurable literacy and school climate turnarounds in historically underprivileged regional districts.
