• Modular, fast, cost-effective for schools/clinics.

Process

1. Background and needs assessment.
2. Conceptual design and item development (CHC + working memory).
3. Pilots and refinement with IRT/Rasch and expert reviews.
4. National validation with CTT/IRT/Rasch.
5. Standardization, norming, final materials.

Features

• ISIS: fluid/verbal/quantitative/visual–spatial reasoning; schools/counseling.
• MAHPAD: knowledge/quantitative/fluid/working memory; preschools/clinics.
• Flexible admin; < 20 minutes; manual/online scoring.
• Child-friendly and counselor-friendly; nationally supported.

Final Outcome

National innovative tools filling a major gap and providing a model for future localized instruments; now official and widely used.
