Fourth Edition
(TONI-4)

Copyright © 2010
The TONI-4 is a practical, easy-to-use, norm-referenced instrument that measures an individual’s intelligence. The administration and response format are pragmatic with simple oral instructions, requiring test takers to answer only with simple but meaningful gestures such as pointing, nodding, or blinking. This test is ideal for those who have language, hearing, or motor impairments, or are not familiar with mainstream American culture. Data was collected from a normative sample of 2,272 people residing in 33 states.The TONI-4 has two equivalent forms: Form A and Form B. Each form consists of 60 items, all of which are abstract/figural (i.e., void of pictures or cultural symbols), thus educational, cultural, or experiential backgrounds will not adversely affect test results. All items are arranged in easy-to-difficult order. Each item contains one or more of the eight salient characteristics: (1) shape, (2) position, (3) direction, (4) rotation, (5) contiguity, (6) shading, (7) size, and (8) movement. Easier items contain one or two characteristics while more difficult items contain several. Both forms can also be used for research purposes and periodic reevaluation.

DEVELOPMENTAL ASSESSMENT OF
YOUNG CHILDREN
Second Edition
(DAYC-2)
by Judith K. Voress & Taddy Maddox
Copyright © 2013
The Developmental Assessment of Young Children - Second Edition (DAYC-2) was developed to identify children birth through 5 years with possible delays in the domains of cognition, communication, social-emotional development, physical development, and adaptive behavior. Each of the five domains reflects an area mandated for assessment and intervention for young children in IDEA. The domains can be assessed independently or as a comprehensive battery to individual children in approximately 20 minutes. The DAYC-2 was normed on a national sample of 1,832 children. Standard scores, percentile ranks, and age equivalents are provided for each domain, and for overall general development if all five domains are tested.

COMPREHENSIVE TEST OF
NONVERBAL INTELLIGENCE
Second Edition
(CTONI-2)
by Donald D. Hammill, Nils A. Pearson, & J. Lee Wiederholt

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, and (6) Geometric Sequences.
Results are reported as standard scores, percentile ranks, and age equivalents. The test was normed on a large (~2827) 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. UNIQUE FEATURES OF THE CTONI-2
- The overall look of the test has been updated and enhanced.
- All new normative data were collected in 2007 and 2008.
- Floor effects have been eliminated.
- Study of item bias has been expanded.
- New oral instructions for common non-English languages in the United States have been provided.

PRESCHOOL AND KINDERGARTEN
BEHAVIOR SCALES
Second Edition
(PKBS-2)
by Kenneth W. Merrell
Copyright © 2002
The Preschool and Kindergarten Behavior Scales-Second Edition (PKBS-2) is a behavior rating scale designed for use with children ages 3 through 6 years. It has two separate scales. The Social Skills scale includes 34 items on 3 subscales: Social Cooperation, Social Interaction, and Social Independence. The Problem Behavior scale includes 42 items on 2 subscales: Externalizing Problems and Internalizing Problems. In addition, 5 supplementary problem behavior subscales are available for optional use. Completion of the rating form takes about 12 minutes and can be completed by a variety of behavioral informants, such as parents, teachers, and other caregivers. Separate score conversion tables are available for home-based and school-based raters.
The PKBS-2 was nationally standardized on 3,317 children ages 3 through 6. Ethnicity, socioeconomic status, and special education classification of the standardization sample approximated those characteristics of the U.S. population, based on the 2000 census. Internal consistency reliability ranges from .96 to .97 for the two scale totals and from .81 to .95 for the subscales. A wide variety of reliability and validity evidence in support of the PKBS-2 is included in the Examiner’s Manual.
