BRIGANCE® Inventory of Early Development III (IED III)

Description

The BRIGANCE® Inventory of Early Development III (IED III) is composed of two instruments: the BRIGANCE Inventory of Early Development III (IED III) and the BRIGANCE Inventory of Early Development III Standardized (IED III Standardized). The IED III is a criterion-referenced measure that assesses children’s skills and behaviors involving physical, language, academic/cognitive, daily living, and social and emotional development. It is designed to help identify children’s strengths and weaknesses, document eligibility for special instruction, track progress, and support program evaluation. The IED III is administered individually and is designed for children from birth through 7 years.

The IED III is organized into skill areas: Physical Development, Language Development, Academic/Cognitive, Daily Living, and Social and Emotional Development. Each skill area includes a brief introduction, assessment method, materials needed, and general recommendations. The individual items are arranged in a large binder. Several skill areas have both Comprehensive and Supplemental Skill Sequences. Comprehensive Skill Sequences provide a detailed skill sequence to evaluate a student’s progress towards mastery or milestone skills. Supplemental Skill Sequences include additional skill practice in naturalistic settings, such as observing a child playing.

The IED III comes with record books for recording and tracking the assessment of each skill behavior. Assessors can use the same record book for six separate administrations to show progress through the use of a color-coded system.

IED III Standardized

The IED III Standardized version offers normative information. The assessments in the standardized version are a subset of those found in the criterion-referenced versions. The IED III Standardized is administered individually to children from birth through age 7. The IED III Standardized assesses children in 5 domains: Physical Development, Language Development, Academic Skills/Cognitive Development, Adaptive Behavior, and Social and Emotional Development. It takes 30-60 minutes to administer.

Development

The IED III is based on previous editions by Albert H. Brigance. Specific information about the development of individual items and changes across revisions is not provided in the source material.

Technical details

The IED III is a criterion-referenced assessment. The IED III Standardized was standardized and validated using a manual published in 2013.

Internal consistency reliability

No information about the internal consistency reliability of the IED III is provided in the source material.

Validity

No information about the validity of the IED III is provided in the source material.

Commentary

The source material does not provide detailed information about the development of the IED III. However, the IED III is noted as a potentially strong assessment tool for organizations and research focused on supporting the development of children across the early childhood continuum (birth to age 7). The source material indicates that the IED III lacks information about its psychometric properties, including reliability and validity evidence. It suggests that evidence is needed to support the reliability of scores and validity of decisions made from IED III results.

Summary

The IED III is a criterion-referenced assessment designed to identify developmental strengths and weaknesses in children from birth through age 7. The IED III Standardized provides normative information. The source material lacks information on the instrument’s development, internal consistency reliability, and validity.
