The TONI-4 aims to measure —the capacity to think logically and solve problems in novel situations—without the confounding factors of verbal or motor skills.
: Two equivalent forms ( Form A and Form B ) allow for progress monitoring or re-testing without practice effects.
"Leo, we’re going to look at some patterns today," Dr. Aris said with a gentle smile. She didn't expect a verbal answer, and she didn't need one. She opened the manual to the first page.
The test utilizes a matrix reasoning format. Each item presents a set of geometric shapes or figures with one missing piece. The examinee must identify the rules governing the relationships between the shapes (such as changes in size, color, orientation, or position) and select the correct missing piece from a set of choices. The puzzles test several problem-solving categories:
: Individuals aged 6 to 89, especially those with communication disorders, autism, or English language learners.
The TONI-4 consists of two equivalent forms (Form A and Form B), each containing 60 items. This dual-form structure allows for reliable retesting or progress monitoring over time without the risk of practice effects.
As they moved through the 60 items, the puzzles grew increasingly complex. What started as simple circles and squares transformed into intricate grids of rotating lines, shifting shadows, and evolving sequences.
to convert Leo’s raw score into a standard score and percentile rank. The results were clear: Leo’s nonverbal intelligence was in the "Above Average" range. He wasn't struggling with cognition; he was simply a bright child locked behind a language barrier.
Once you have filled out the PDF record form and calculated the raw score, you will generate a (Mean = 100, SD = 15). This is a classic IQ-style metric.
Ideal for individuals with aphasia, hearing impairments, or those who are non-native English speakers.

Because the TONI-4 eliminates language barriers, it provides an unbiased assessment of cognitive ability for individuals who cannot be fairly evaluated by traditional IQ tests. It is highly beneficial for:
