As a norm‐referenced assessment tool, the Learning Accomplishment Profile‐Diagnostic (LAP‐D) Third Edition provides a systematic method for observing individual development of children functioning in the 30 to 72 month age range. Teachers, special educators, clinicians, parents, and other professionals can use the LAP‐D to provide a context for understanding individual skill development in comparison to the standardization sample. In addition, the results of the LAP‐D can be used to plan and implement individualized, developmentally appropriate activities for children in educational and/or home settings.

The LAP‐D is designed for children both with typical and with atypical development. Standard scores produced by the LAP‐D include T‐score, NCE‐score, Z‐score, Percentile‐rank score, and Age‐equivalent score. Standardized materials, procedures, and criteria for determining a child’s level of functioning are included for each item to help ensure consistent and accurate results. The LAP‐D may be administered in English or Spanish and includes separate norm‐tables for each language.


The LAP‐D consists of a total of 226 developmental skills arranged hierarchically in four domains of development, with two subscales in each domain:


  • Fine Motor
  • Cognitive
  • Language
  • Gross Motor


  • Writing
  • Manipulation
  • Counting
  • Matching
  • Naming
  • Comprehension
  • Body Movement
  • Object Movement
  • Early Childhood Considerations

The LAP‐D is appropriate for children functioning in the 30 to 72 month age range. Children with disabilities who are older than 72 months may be assessed using the LAP‐D if observational data or other diagnostic evaluation data indicate they are functioning in the 30 to 72 month age range. However, for children older than 72 months, the standard scores should not be used.

The LAP‐D may be administered in either English or Spanish. Both the English and Spanish versions were standardized on separate national samples of children based on the primary language of each participating child. During the past decade, many factors have changed in the overall population of the United States and the provision of early childhood services. Without a doubt, these changes had an impact upon the psychometric properties of the LAP‐D, which was previously standardized in 1992.

Furthermore, the significant increase in the Latino population in the United States during the past decade (U.S. Census, 2000) has led to the need for a Spanish edition of the LAP‐D. The research included representative samples of both English‐ and Spanish‐speaking children in order to re‐norm the LAP‐D in English as well as to develop and establish norms for the LAP‐D in Spanish. Furthermore, psychometric properties, such as test construction, reliability, and validity, were examined for both the English and Spanish versions to ensure the technical competence of the LAP‐D for each language group.

LAP-D Reports

One of the most profound challenges in early childhood is aligning developmentally appropriate curriculum with high quality interactions focused at the developing level of each child’s growth and learning, including those with special learning needs.

Several considerations are important when meeting goals for this type of effective early learning instruction. Effective teaching builds upon children’s current level of understanding, creates links among multiple skills, and is responsive to the individual learning needs of each child. Information gathered from LAP-D 3rd Edition assessments provides the information critical to supporting this process.
