The Learning Accomplishment Profile - Diagnostic Edition (LAP-D) provides a systematic method for observing children functioning in the 30-72 month age-range. The purpose of this normed-referenced assessment is to assist teachers, clinicians, and parents in assessing individual skill development in four major developmental domains (each contains two subscales): gross motor, fine motor, cognitive, and language.

The results of the LAP-D can be used to generate a complete picture of a child's developmental progress so that individualized, developmentally appropriate activities can be planned and implemented. This assessment is designed for children with typical and atypical development.>>Back to Top.
Child Assessment
Because this is a norm-referenced instrument, administrators should adhere to the written protocol for each item to assure reliability. A station approach may be used and the instrument may be given at various times to an individual child as long as the protocol for each item is followed carefully. Other considerations include:
  • Administration time takes between 1 and 1.5 hour to complete.
  • The LAP-D should be administered by trained professionals or paraprofessionals
  • The instrument may be administered at specific intervals to monitor progress
  • The LAP-D may be used with children who are functioning in the 30-72 month developmental age-range even when their chronological age is older. >>Back to Top.

The LAP - Diagnostic Edition contains a hierarchy of 226 developmental skills arranged in chronological sequence in four domains of development:

Fine Motor
Gross Motor
Writing (31 items))
Manipulation (28)
Counting (33) Matching (24)
Naming (30)
Body Movement Object (34) Movement (23)

Child Assessment
As a norm-referenced assessment, the LAP - Diagnostic Edition has a number of useful applications for the evaluation and instruction of young children. LAP-D results may be used in the following ways:
  • To determine a child’s developmental age in relation to his/her chronological age in the various domains.
  • To provide individual skill development information for planning developmentally appropriate activities at home and school based on a child's performance relative to a standardized score. Identification of developmental levels assists teachers in determining the appropriate "starting point" in curriculum planning.
  • To assist in the identification of children with disabilities and the subsequent development of an IEP when used as a part of a multi-disciplinary evaluation. The appropriate evaluation of young children should utilize both informal (e.g., observation, work samples) in addition to formal techniques such as the LAP-D.
  • To evaluate a child's entry and exit skills and/or to validate the intervention program. As a pre-assessment measure, the LAP-D is a consistent record of the skills the child has mastered prior to admission into the program. As a post-assessment measure, the LAP-D is useful for the determination of a child's progress and may be useful to parents, teachers, and program evaluators in determining if the instructional program is having a beneficial effect on the child's development.
  • To conduct research on the development of preschool, kindergarten, or special needs children.
  • To train teachers, paraprofessionals, clinicians, and parents on developmentally appropriate assessment practices.
  • To assist early childhood programs in meeting national and state requirements (e.g., Head Start Child Outcomes, state standards). >>Back to Top.

LAP-D Assessment Materials
Child Assessment
Eight LAP - Diagnostic Edition manuals (one for each subscale) form the core of the assessment. Each manual includes:
  • a materials list for each domain
  • procedural instructions for administering individual items
  • scoring criteria for each item
  • summary pages, and
  • a developmental profile page. >>Back to Top.

Scoring Booklet
LAP-D scoring booklets can be used for recording the results of the assessment. Scoring booklets contains an abbreviated form of each item name in the same sequential order as the manual and space for scoring assessment results, a comment column, and a developmental profile. The LAP-D scoring booklet is NOT an assessment instrument. It must be used in conjunction with the LAP-D Assessment Manuals, which contains the procedures, materials needed, and scoring criteria for each item.
Child Assessment
Assessment Kit
The dimensions of materials needed to administer the LAP - Diagnostic Edition are specified at the beginning of each assessment item. A standard LAP-D kit can be purchased from Kaplan Early Learning Company or Red-E-Set-Grow. The LAP-D kit includes most of the necessary materials (except large items such as furniture or stairways).
Child Assessment
LAP-D Planning Cards
The LAP-D Planning Cards are a set of sequential cards correlated with the LAP-D, one card for each item. Each card describes multiple developmentally appropriate learning activities that supporting skill development across skill and subject areas.
Child Assessment
Spanish Materials
The Spanish edition of the LAP-D is available. The LAP-D Planning cards are also available in Spanish. >>Back to Top.

Instructions for Using the Profile
After the pretest is completed, the examiner can use the profile chart to graphically show the results.
Using a colored marker, color in each box that represents an item that was completed successfully by the child. Also color in all items to the left of those actually administered (this is the basal--check the instructions) because it is assumed that the child would have accomplished these easier, lower level items had they been administered. The numbers by the boxes match the numbers of the items in each skill area. Not all the boxes have numbers. Item 16, for example is the box to the right of item 15, item 17 is two boxes to the right, and so forth.
Then, at the end of the program year or some other later time, administer the "post test" and color in the boxes that represent the items passed with a different, contrasting color. The result will give a graphic representation of the child's progress.>>Back to Top.
Child Assessment
Validity and Reliability
In 2005, a study was completed that demonstrates the validity and reliability of the LAP-D diagnostic assessment. The resulting 123-page Examiner’s Manual and Technical Report is available from Kaplan. The report includes statistics for:
  • Internal consistency
  • Test-retest reliability
  • Inter rater reliability
  • Construct and criterion validity
  • Percentile ranks
  • Age equivalent scores
  • Z and T-scores
  • Normal curve equivalents >>Back to Top.
Child Assessment
Software has been developed to assist teachers in using the LAP-Diagnostic Edition as an on-going assessment tool in the preschool classroom. This software assists teachers in developing:
Individual assessment results and summaries for:
  • Classroom profiles
  • Parent reports
  • Group and individual progress charts
  • Links to developmentally appropriate activities
  • Individual, classroom, and center analysis of assessment results in relation to the Head Start Child Outcomes
Computer scoring assistant software is available in either in a web-based or CD-Rom format. An electronic scoring protocol is also available using a Palm Pilot application which facilitates using the LAP-D as an ongoing assessment tool. For additional information on LAP software go to
