the LAP-D Third Edition is <strong>com</strong>prised of four domains, each of which is divided into twosubscales, exactly as the previous edition. Similarly, the same developmental milestones areincluded on both the second and third editions. However, changes in the placement within andbetween developmental age categories were made for 22 items based on study results to ensurethe appropriate sequence of items and developmental age levels.Another difference is the addition of the Spanish version of the LAP-D, and presentation of theinstrument in a dual language format. The Spanish translation/adaptation of the LAP-D wasmatched to the English version as closely as possible. Developmental milestones are the same onboth instruments; however, in some cases the content of the Spanish version differs from theEnglish version to ensure its cultural and linguistic integrity. For example, different words wereused in the Spanish version when the translation was not developmentally or culturallyappropriate. Similarly, the same illustrations and manipulative materials are used with eachlanguage except for items CM21, CM24, LN30, and LC23.A third difference between these two editions of the LAP-D is the organization of the assessmentkit. The LAP-D is provided in a dual language kit that includes all the necessary materials foradministering the LAP-D in either English or Spanish, except for environmental items like stairsor chairs. Unlike the second edition, the third edition of the LAP-D has one Examiner’s <strong>Manual</strong>and one container with all kit contents rather than separate manuals and kit materials for eachsubscale. The Examiner’s <strong>Manual</strong> for the third edition has English text on one side and Spanishtext on the other side. LAP-D illustrations are contained in a separate book rather than in theExaminer’s <strong>Manual</strong> as they were in the previous edition.Lastly, new norms tables were developed for scoring and interpreting LAP-D results for theEnglish and Spanish versions, with separate tables for each language group. (See page 77 for thenorms tables.)Applications of LAP-DAs a norm-referenced assessment, the LAP-D has a number of useful applications for theinstruction of young children. LAP-D results can be applied in the following ways:• To provide individual skill development information for planning developmentallyappropriate activities at home and school based on a child’s performance relative to astandardized score. Identification of developmental levels assists teachers in determiningthe appropriate “starting point” in curriculum planning.• To evaluate a child’s entry and exit skills and/or to validate the intervention program. Asa pre-assessment measure, the LAP-D is a consistent record of the skills the child hasmastered prior to admission into the program. As a post-assessment measure, the LAP-Dis 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 abeneficial effect on the child’s development.4
• To assist in the identification of children with disabilities and the subsequentdevelopment of an IEP when used as a part of a multi-disciplinary evaluation. Theappropriate evaluation of young children should utilize both informal (e.g., observation,work samples) and formal techniques such as the LAP-D (NAEYC & NAECS/SDE,2003).• To conduct research on the development of preschool, kindergarten, or special needschildren.• To train teachers, paraprofessionals, clinicians, and parents on developmentallyappropriate assessment practices.• To assist early childhood programs in meeting national and state requirements (e.g., HeadStart Child Out<strong>com</strong>es, state standards)Limitations of the LAP-DThough the LAP-D has many possible applications, the examiner should apply some basicprinciples in its use. The LAP-D should never be used as a single measure for makingeducational decisions; rather, it should always be used in conjunction with a variety of formaland informal assessment procedures administered by different individuals.Children functioning at the lower end of the age range (below 36 months) may be more fullyevaluated using the Early LAP, which is designed to assess children birth to three years of age.For these children, the Early LAP assesses a wider range of behaviors below the 36-month agelevel.User QualificationsThe LAP-D is a norm-referenced instrument with clear guidelines for administration. Careshould be taken to follow these specified guidelines in order to achieve the most accurate results.Administration of the LAP-D does not require specific licensure or certification; however,training and/or experience in assessment procedures is essential for effective administration.Trained teachers, paraprofessionals, clinicians, special educators, psychologists, occupationaland physical therapists, speech-language pathologists, and others familiar with childdevelopment can administer the LAP-D. To ensure appropriate and accurate use of assessmentinformation from the LAP-D, the examiner must be<strong>com</strong>e thoroughly familiar with theExaminer’s <strong>Manual</strong> & <strong>Technical</strong> <strong>Report</strong> through self-study or professional training. TheStandards for Educational and Psychological Testing (1999) re<strong>com</strong>mends that test users “studyand evaluate the materials provided by the test developer (p. 113).” The Standards especiallyemphasize knowing the purposes, administration procedures, and appropriateness of theassessment for specific populations, as well as the reliability and validity of the assessment. Inaddition, examiners should practice administration of the assessment to help develop or improvethe skills necessary for effective administration.5
