iSophi BANT (Brief Adaptive Nonverbal Test) is a modern, fast and objective diagnostic tool designed for early screening of nonverbal intelligence in children of preschool and early school age (from 4 to 7 years).

The application monitors the child's cognitive potential and his ability to learn new things completely independently of language skills, speech development or learned vocabulary. Thanks to this, the test is as fair as possible even for children with a different mother tongue (OMJ), speech therapy defects or significant shyness.

🚀 Key features and benefits:
Unique adaptive algorithm (CAT): The test adapts to the child's abilities in real time. If he answers correctly, he gets a harder task; if he makes a mistake, the system offers him an easier challenge.

Extreme time saving: The entire test takes only 3 minutes on average. The child does not get tired and maintains full attention.

Comfort without frustration: The adaptive system ensures that the child experiences a sense of success and is not confronted with tasks that are too difficult for him.

Cultural and linguistic fairness: The test does not require spoken words or understanding of complex language.

Comparison with the national norm: The child's performance is immediately compared with the results of hundreds of children of the same age in the Czech Republic.

📊 Who is iSophi BANT intended for?

Screening results offer immediate feedback and generate detailed reports tailored for:

Psychologists and special educators: Detailed psychometric data (Sophi-score, derived IQ, percentiles and 90% confidence intervals compatible with complex batteries such as WISC-V).

Kindergarten and elementary school teachers: Objective basis for early recognition of developmental risks (weakness) or, conversely, extraordinary talent. Great as a basis for communication with parents.

🛡️ Scientifically based quality
The tool was developed by leading Czech experts and its psychometric quality is based on the Item Response Theory (IRT). The methodology fully complies with the International Standards for Educational and Psychological Testing. More detailed theoretical information can be found in the academic article in the journal Czechoslovak Psychology (2025).
