The most comprehensive localized and standardized tool for assessing intelligence and cognitive abilities from childhood to adulthood

The Iran–Stanford–Binet Intelligence Scale, Fifth Edition, was developed under the commission of the Strategic Headquarters for the Development of Cognitive Sciences and Technologies and with the support of the Vice-Presidency for Science, Technology, and Knowledge-Based Economy. This test is the most authoritative localized version of the Stanford–Binet scale, designed to provide precise assessment of cognitive abilities for individuals from 2 years old to 85 years and above.

Grounded in the Carroll–Horn–Cattell (CHC) theory of intelligence and advanced Rasch modeling, the test employs a multidimensional approach, comprising ten verbal and non-verbal subscales. Through this structure, it provides Full Scale IQ, Verbal IQ, Non-Verbal IQ, and five key cognitive indices (Fluid Reasoning, Knowledge, Quantitative Reasoning, Visual–Spatial Processing, and Working Memory), all measured in both verbal and non-verbal domains. This allows for a detailed analysis of individual cognitive ability profiles.

Applications

• Identifying gifted children and evaluating cognitive delays
• Planning educational and therapeutic interventions tailored to individual needs
• Screening for learning disabilities, autism, and ADHD
• Human resources applications for cognitive assessment and talent identification
• Developmental psychology research and test construction
• Informing educational and cognitive health policymaking
• Supporting parents in understanding their children’s cognitive abilities

Advantages

• The only nationally standardized and localized intelligence test in Iran
• Comprehensive and precise evaluation based on the latest scientific theories
• Flexible administration for diverse age groups and cultural contexts

With strong scientific foundations and national support, the Iran–Stanford–Binet Intelligence Scale (Fifth Edition) is a modern and comprehensive tool for assessing and fostering the country’s human capital.

The Iranian Short Intelligence Scale (ISIS) is a national and innovative tool in the field of cognitive assessment, designed for students aged 12 to 18. With speed, accuracy, and cost-effectiveness, it measures key domains of intelligence and cognitive abilities. Developed based on the comprehensive Cattell–Horn–Carroll (CHC) theory of intelligence, ISIS evaluates four core areas: Fluid Reasoning, Verbal Reasoning, Quantitative Reasoning, and Visual–Spatial Processing.

Features and Advantages

• Fully localized within Iran’s cultural and educational context, with national standardization
• Group administration possible without the need for a professional examiner
• Flexible implementation: paper-based or computer-based, individual or group formats
• Short administration time with appropriate cognitive load for children and adolescents
• Applicable across diverse settings: schools, psychology clinics, counseling centers, and population-based research

Applications

• Rapid screening of cognitive abilities and identifying learning weaknesses
• Helping schools recognize talents, guide academic pathways, and support educational advancement
• Early detection of cognitive and learning problems by counselors and psychologists
• Use in developmental psychology, cognitive science, and educational research
• Supporting educational policymaking and national talent identification initiatives

Main Users: Students, teachers and school counselors, psychologists, academic researchers, the Ministry of Education, the Organization for Exceptional Education, psychology clinics, psychometric service centers, and families. With its simple, scientific, and practical design, ISIS provides broad access to valid cognitive assessments and stands as one of the few official national tools for intelligence measurement in Iran.

MAHPAD is a scientific, concise, and engaging tool for assessing the cognitive abilities of preschool children (Pre-1 and Pre-2), designed to prepare them for successful school entry. Developed within CHC and analyzed using the Rasch model, it evaluates four key domains: Fluid Reasoning, Quantitative Reasoning, Knowledge, and Working Memory.

Features

• Designed and fully localized with culturally relevant images and short stories for Iranian children
• Can be administered individually or in groups, paper-based or digital, within a short time (up to 30 minutes)
• Attractive graphics and play-like activities reduce stress and increase motivation
• Fast scoring with standardized reports based on national norms
• Usable even in under-resourced settings

Applications

• Early screening in kindergartens and preschools
• Identify strengths/weaknesses for targeted support
• Help parents make informed decisions
• Use in developmental research and population studies
• Support preschool education policy

Main Users: child psychologists, preschool teachers/administrators, diagnostic centers, researchers, parents and families, and policymakers; IPIS supports accurate assessment and successful school transition.

The Early Literacy Skills Test is a standardized tool designed to assess the foundational components of reading and writing in preschool children. It is intended for children aged 4 to 5 years and 11 months, particularly those who face challenges in developing the essential skills required for entry into elementary school. Administering this test before the end of the preschool period provides the most accurate estimate of a child's abilities and plays a key role in preventing future learning difficulties.

Why is this test important?

Early reading and writing skills are the foundation of academic learning. Children who acquire these skills before starting school progress faster and achieve greater success in education. Conversely, weaknesses in these skills may lead to learning disabilities and reduced self-confidence.

Areas of Assessment

1. Visual Perception: including spatial relations, visual discrimination, figure-ground differentiation, visual closure, visual memory, and form constancy.
2. Phonological Awareness: the ability to recognize sounds and syllables essential for word formation and language learning.
3. Alphabet Knowledge: recognizing the names, sounds, and symbols of letters necessary for learning to write.
4. Phonological Memory: the ability to store and process verbal and auditory information.
5. Print Concepts: understanding and recognizing the role and form of printed text and the relationship between spoken and written language.
6. Rapid Automatic Naming: the ability to quickly retrieve information from memory and rapidly name sets of images.
7. Name Writing: the child's ability to independently write the letters of their own name.

Applications

• Early screening of skills required for school readiness
• Predicting academic success in the early years of schooling
• Helping teachers and parents design supportive and enrichment programs
• Reducing the risk of learning disabilities and academic difficulties in the future

The Early Math Skills Test is one of the most important assessment tools in preschool years and is recognized as the strongest predictor of future academic achievement in both mathematics and reading. Research shows that weak foundational math skills not only hinder the understanding of more complex concepts such as fractions and algebra but also accumulate and worsen over time. In contrast, acquiring early math skills in the first years of life is the key to cognitive growth and future academic success.

Why is this test important?

Learning math in early childhood not only strengthens cognitive abilities but also nurtures curiosity, creativity, persistence, and flexibility. Positive early experiences in mathematics lay the foundation for future learning and long-term success in school.

Areas of Assessment

1. Basic Concepts: understanding spatial and positional relations.
2. Geometric Shapes: recognizing 2D/3D shapes.
3. Colors: primary, secondary, complementary.
4. Similarities and Differences.
5. Associations.
6. Pattern Recognition.
7. Numbers and Counting.
8. Addition and Subtraction (single-digit).
9. Measurement: biggest/smallest, tallest/shortest, etc.

Applications

• Early screening of mathematical readiness
• Predicting academic success
• Targeted educational support programs
• Preventing later math difficulties
