For over 20 years, professionals working with infants and toddlers have relied on the proven Bayley Scales of Infant Development. And today, they have even greater reason to do so. With the new Bayley–III, professionals have the most comprehensive assessment tool for determining developmental delays in children one month to 42 months old.

Bayley-III Complete Test

Easy to Use.
Hard to argue with.

Unlike other solutions that have manipulatives that can be cumbersome or time consuming, Bayley–III is easy to use and to transport. It’s also very easy to administer, and the results are exceedingly reliable. It is administered using a caregiver’s or parent’s involvement, allowing more input to be gathered from the child’s natural environment. Additionally, all assessment factors are based on the age of the child, allowing for more accurate developmental assessments.

New Design!

FAQs

Questions

Frequently asked questions follow. Click on a question to see the response.

Test Content

  • How much overlap is there between the Preschool Language Scale—Fourth Edition and the Bayley–III Language Scale?

    There are only 44 items in the Bayley–III Language Scale that originated from the PLS-4. A validity study between the PLS–4 and the Bayley–III indicate no practice effects between the two tests, so administration of one test does not affect performance on the other test.

  • Where can I find additional interpretive guidelines for the Social-Emotional Scale?

    For additional interpretive guidelines specific to the social-emotional score, Dr. Greenspan includes some "next steps" within the manual for the Greenspan Social-Emotional Growth Chart. The material is adapted from what is found in books authored by Dr. Greenspan (including Building Healthy Minds and The Functional Emotional Assessment Scale for Infancy and Early Childhood).

Administration

  • Can all items that use the same materials within an age group be administered one after the other (e.g., all items that use blocks), similar to the BSID–II administration format?

    Because the items are ordered by difficulty, administer the items in each subtest in the order listed (with the exception of series items). The subtests were standardized by having examiners follow the item order provided. It also ensures that all pertinent items are administered (none are forgotten), and that reversal and discontinue rules are met quickly, with no extraneous items that may contribute to the fatigue of the child.

  • There is an item on the Bayley–III video that shows the examiner positioned across from the child, when the Administration Manual indicates that for the item, the examiner should be positioned next to the child. Which directions should I follow?

    The item in question is "Uses pencil to obtain object." The examiner should position him- or herself alongside the child, to give the child the proper perspective. In all instances, the directions in the Administration Manual should be followed.

  • Why is it recommended to administer the Receptive Communication subtest prior to the Expressive Communication subtest?

    Statistically, we did not find practice effects based on subtest order for any subtests. The number of items that can be scored through observation of the child also minimizes the likelihood of practice effects with the Communication subtests. However, there are some reasons for recommending that Receptive Communication be administered prior to Expressive Communication. Some stimulus items are similar across content and repeated exposure to these pictures may make it easier for the child to recognize them in the Receptive Communication subtest. In addition, many young children must establish rapport with the examiner before expressing themselves vocally by naming objects or speaking to the examiner; the Receptive items can help familiarize the child with tasks and encourage vocalizations.

  • There are a number of items that can be considered sequential that either are not marked as sequential, or are only partially noted as sequential (i.e., later items in the “sequence” not listed). Why aren’t these noted as series items?

    Items are marked as series items only if the administration is exactly the same for each item in the series. That is why the Rotated Pink Board is not identified as part of the Pink Board Series.

  • How soon can the Bayley–III be readministered in order to measure growth?

    The types of items administered to infants are unlikely to be "learned" or to produce practice effects, so children can be readministered the Bayley–III in a shorter time frame. An interval of approximately 3 months is recommended for children under 12 months of age; an interval of approximately 6 months is recommended for children older than 12 months, although shorter intervals can be used if warranted.

  • What start point should an examiner use when testing a child with suspected deficits?

    The start points were chosen to accommodate most children with some degree of delay. If the examiner suspects sufficient delays such that the child will likely reverse, the examiner can begin one start point below the age-appropriate start point, and reverse as needed. It is not recommended that the examiner begin administration any earlier, in order to eliminate the possibility of multiple basals.

  • Is the Language Scale sufficiently comprehensive so that additional language assessment is not necessary, especially for the younger children?

    The Language Scale is sufficient for determining if a language problem exists. It may also indicate what language problem it is likely to be. However, in order to pinpoint the problem to determine appropriate intervention (particularly if referring to a Speech Language Pathologist), additional assessment will be necessary. The Preschool Language Scale—Fourth Edition is one instrument that can be given if the Bayley–III Language Scale indicates delays.

  • What was the rationale for adjusting prematurity up to 24 months?

    It was a combination of evidence from the literature and recommendations from the Bayley–III advisory panel. Discussions for adjusting to prematurity to 24 months of age began early in the development process of the Bayley–III and follows the same recommendations made for the BSID–II. The adjustment for prematurity was not taken beyond 24 months because the advisory panel and the literature indicate the vast majority of children "catch up" by 24 months of age.

  • Can children be administered the Bayley–III in the home setting?

    The Bayley-III CAN be administered in the home, but the examiner must maintain standard procedures and keep distractions to a minimum.

  • For children ages 2:6–3:6, both the Bayley–III and the Wechsler Preschool and Primary Scale of Intelligence—Third Edition (WPPSI–III; Wechsler, 2002) could be administered. Which instrument should be used for this age range?

    Which test to use depends on your clinical judgment and the purpose of testing. Practitioners can use either or both instruments for children ages 30–42 months (2 years 6 months and 3 years 6 months). Though both measures provide an estimate of a child’s cognitive functioning, the instruments are designed for different purposes. The Bayley–III provides information about whether a child’s developmental trajectory in the cognitive domain is proceeding as expected, relative to same-age peers. It also provides this type of information for language, motor, social-emotional, and adaptive behavior domains. The WPPSI–III is specifically designed to measure a child’s overall cognitive ability, as well as his or her cognitive ability in more specific domains (e.g., verbal, perceptual, processing speed). The Bayley–III should be used to evaluate cognitive ability in low-functioning children in this age range because it provides an extended floor. The WPPSI–III should be used to evaluate cognitive ability in high-functioning children in this age range, because it provides an extended ceiling. If results of the Bayley–III suggest delays in the cognitive domain, the WPPSI–III may provide additional information on the specific areas of cognitive ability that are problematic for the child. If an ability score (e.g., FSIQ) is required, the WPPSI–III should be used.

Scoring

  • Will there be Cognitive-Language Composite score similar to the BSID–II MDI? Is there an overall score available?

    At this point, there are no plans to develop either a Bayley-III Cognitive-Language composite score that corresponds with the BSID-II MDI or an overall composite. The reasoning behind separating the scores is because at this young age it is important to distinguish between delays related to language difficulty and those related to cognitive difficulty. U.S. federal mandates, such as IDEIA, emphasize the need to provide scores for the individual domains, rather than a global composite score. A composite score can also mask delays if one area is strong while the other is weak.

  • If the Social-Emotional Scale on the Bayley–III is the same as the Greenspan Social-Emotional Growth Chart, why are there different scores available for the two instruments?

    The difference between the Greenspan Social-Emotional Growth Chart and the Bayley–III Social-Emotional Scale is that the Greenspan Social-Emotional Growth Chart provides only cut scores; the Bayley-III provides scaled scores for this measure.

  • Can an examiner accept baby signs/ASL as words on the Expressive Communication Scale?

    Many of the Expressive Communication items indicate that approximations (the implication being verbal approximations) can be accepted. If the child is capable of speaking, the child should be prompted to use spoken words rather than signs. If, however, the child is signing as an accommodation, then the clinician would need to take that into account when interpreting the results.

  • What is the difference between a score of 0 (can’t tell) and 1 (none of the time) for the Social-Emotional Scale?

    The score of 0 should be chosen if the respondent doesn't feel he/she knows the child well enough to respond with confidence (lack of familiarity with the child or limited settings in which the respondent has observed the child). The score of 1 should be chosen if the respondent is familiar enough with the child to know that the child never exhibits those behaviors.

Software

  • Can the Bayley–III Scoring Assistant® software be used without the PDA administration?

    Administration of the Bayley–III using the PDA is not necessary in order to use the Scoring Assistant (although they are packaged together). Users can enter raw scores into the Scoring Assistant to obtain the tables and graphs report.

Multi-Disciplinary Evaluation

  • Why are there separate Record Forms for each of the Cognitive, Language, and Motor Scales? Are they different from what is contained in the comprehensive Record Form?

    A separate Record Form is available for each Scale in order to provide flexibility for customer needs. For instance, these record forms can provide more efficiency when conducting research, and for multidisciplinary and arena assessment teams. The standard Record Form (combining all 3 Scales) contains all the information and items found in the individual Record Forms.
