The CTONI-2
is a popular norm-referenced test that uses nonverbal formats to
measure general intelligence of children and adults whose performance on
traditional tests might be adversely affected by subtle or overt
impairments involving language or motor abilities. The CTONI-2
measures analogical reasoning, categorical classification, and
sequential reasoning, using six subtests in two different contexts:
Pictures of familiar objects (e.g., people, toys, animals) and geometric
designs (unfamiliar sketches and drawings). The six subtests are:


  1. Pictorial Analogies
  2. Geometric Analogies
  3. Pictorial Categories
  4. Geometric Categories
  5. Pictorial Sequences
  6. Geometric Sequences.


Results
are reported as standard scores, percentile ranks, and age equivalents.
The test was normed on a large (~2,827) representative national sample
that was stratified by age. The reliability coefficients of its
composite are mostly in the .90s with a few in the high .80s. It
correlates with most well known intelligence testing in the high .70s.
Considerable other validity evidence is provided in the manual.
