Brigance – Early Childhood – IED III

Inventory of Early Development (IED) III

Criterion-referenced assessment
(Birth–7 years 11 months)

Easily monitor individual progress toward common early learning standards or foundations and plan developmentally appropriate, individualised instruction. The comprehensive, user-friendly BRIGANCE® Inventory of Early Development III provides teachers with a flexible, valid and reliable ongoing assessment of school-readiness skills.

The IED III criterion-referenced assessment measures a student's performance based on mastery of a specific set of skills. It measures what the student knows and doesn't know at the time of assessment. The student’s performance is NOT compared to other student's performance on the same assessment.

The BRIGANCE IED III has more than 100 assessments that cover a broad sampling of students' skills and behaviours in key academic and developmental domains.

Age ranges are determined by developmental age, meaning the IED III can be used with any student – regardless of chronological age – who functions at a level from birth through to the developmental age of seven years and 11 months.

Using the criterion-referenced assessments for ongoing assessment throughout the academic year allows a comparison of a student's current skill mastery to their skill mastery at previous points in the year. Due to skill sequences being broken down into gradual steps along the skill continuum, progress can be measured in very small increments.

Detailed overview

The BRIGANCE Inventory of Early Development (IED) III is a comprehensive collection of valid, reliable and well-researched developmental assessments for children from birth to seven years and 11 months of age. The IED III produces a complete range of information on a child’s developmental progress through distinct developmental skill sequences performed in authentic, everyday conditions.

The assessments in the IED III allow teachers to pinpoint individual areas of strength and need. Teachers can then identify a sequence of instructional objectives for planning developmentally appropriate instruction, individualising ongoing assessment and monitoring progress. Assessment items in the IED III cover a broad sampling of a child’s skills and behaviours. Key developmental areas are aligned to common early learning standards.

Assessments cover the following domains:

  • Physical development
  • Language development
  • Literacy
  • Mathematics and science
  • Daily living
  • Social and emotional development
  • Approaches to learning


The IED III is a criterion-referenced measure designed to measure a child’s performance compared to specific educational objectives. Criterion-referenced tools provide data on what a child knows in relation to certain specified skills.

Key developmental assessments in the IED III have been standardised and validated for children from birth to seven years of age and appear in the IED III Standardised. If you wish to derive standard scores, percentiles and age equivalents, see the norm-referenced IED III Standardised and its accompanying Standardised Record Book.

Key features of the IED III:

  • Assessments include customisable instructional objective statements for planning instruction, writing IEPs/IFSPs and charting growth.
  • Comprehensive Skill Sequences list intermediate skills along with milestone skills, enabling teachers to show incremental progress for every child.
  • Supplemental Skill Sequences provide additional skills to illustrate progress.
  • The Milestone Skills by Developmental Age Level section organises key skills by age, providing a snapshot of child development across domains.
  • The Record Book that accompanies the IED III provides a record-keeping and tracking system for each child that is ongoing, specific, graphic and easily interpreted.
  • The Record Book also allows teachers to record observations and make notes about the child’s initiative, curiosity, engagement, persistence, reasoning and problem-solving skills.
  • The BRIGANCE Online Management System provides a means for tracking and reporting individual and group progress (subscription rates apply).


The IED III helps early childhood educators

  • address ongoing developmental assessment requirements.
  • provide an appropriate child assessment system that aligns with common standards and goals.
  • determine a child’s specific strengths and needs to support individualised instructional planning.
  • gather valid data on a child’s progress.
  • evaluate school readiness by tapping predictors of school success.
  • communicate a child’s development to parents/caregivers.
  • support referrals for further evaluation or special services.
