Peer Reference Report for Infants and Toddlers: Family Guidance

Overview of the DRDP (2015)

You may have heard about the DRDP from your child’s early interventionist. “DRDP” stands for the “Desired Results Developmental Profile.” The DRDP (2015) is a tool that early interventionists use to record information about your child’s learning and development.

Early interventionists complete the DRDP (2015) two times each year by observing children during everyday activities at home, in child care, or at preschool. These observations are used to complete the items on the DRDP (2015). You might also be asked to share what you see your child doing.

The DRDP (2015) looks at six areas of children’s development, called domains. The domains are:

  • ATL-REG: Approaches to Learning and Self-Regulation – how children learn in the classroom.
  • SED: Social and Emotional Development – how children get along or play with others.
  • LLD: Language and Literacy Development – how children communicate and are learning to read.
  • ELD: English-Language Development – how children learn English if another language is spoken at home.
  • COG: Math– how children learn about numbers and counting.
  • PD-HLTH: Physical Development and Health – how children move around and learn to do things on their own.

Each domain is made up of measures. Measures describe the steps children follow to learn important skills in a domain. For example, learning to play with others (“Relationships and Social Interactions with Peers”) is one measure in the Social Emotional Development domain.

You can participate in the DRDP (2015) assessment in many ways:

  • Share the things you see your child doing during everyday activities with your child’s early interventionist. Perhaps you heard your child counting during playtime; or when dressing, you saw your child sit by herself. You can share what you noticed, as well as stories, photos, drawings, or videos.
  • Talk with your child’s early interventionist about what your child does well and what you want to focus on.
  • Talk about the DRDP (2015) results at parent conferences and meetings and ask questions.
  • Talk with your child’s early interventionist about what to expect next for your child’s learning and development.
  • Make sure that your child’s early interventionist knows about the things your child uses to help with everyday activities. Examples are a special spoon or larger print. These are known as adaptations.

Children, early interventionists, families, and others benefit from the DRDP (2015).

  • Your child benefits from the DRDP (2015) because your child’s early interventionist uses the information to help your child learn.
  • Your child’s early interventionist will have up-to-date information to help plan your child’s learning activities.
  • The benefit to you is that your child’s early interventionist will share your child’s progress with you using the DRDP (2015) child reports. You will then know more about your child’s development and ways to support your child’s learning.
  • The California Department of Education will know how children are making progress in its programs, and can make sure that its programs are high quality.

About the Peer Reference Report

The Peer Reference Report compares your child’s DRDP (2015) results to a group of children in the same age range. These age ranges are shown as age bands in the report. For example, if your child is 13 months old, you can see her results are in the 0-24 month age band. This report shows areas of strength as well as those that may need more support. As you look at this report, think about what your child can do and share what you know with your child’s early interventionist.

What You See on the Peer Reference Report

The different elements of the report are described below.

  • The DRDP (2015) date and your child’s age are at the top of the page.
  • Each domain appears in a box. Next to each box is the name of the domain and what it is about.
  • Your child’s ratings for all the measures in a domain are combined into a domain rating. The long line in each box is your child’s domain rating.
  • The line going across the domain rating is the "standard error of measurement" and is often shown for assessments like the DRDP (2015). For the DRDP, it is likely that your child’s “true” domain rating falls within the range of ratings shown by the line.
  • Each box has long bands for every age group. These are age bands. The band for the youngest children, 0-24 month olds, is at the bottom of each box. Every other band is a 12-month band.
  • Your child’s age band is highlighted and it matches your child’s age at the time of the DRDP (2015) assessment.
  • The short line going up and down in the middle of the dark part of the age band shows how well children in that age band are doing, on average, in that domain. This is the age-group mean or average.
  • If a domain scale does not have a marker, not all measures were rated within the domain. This may happen, for example, if your child has been absent from the program for a long period of time so the early interventionists were not able to observe your child in everyday activities.

How to use this Report

  • In each box, find your child’s domain rating in his or her age band.
  • Find your child’s domain rating in his or her age band. These markers in the darker part of the band show your child’s domain score to be within age expectations. The markers in the lighter part of the band are close to age expectations.
  • Markers that are not in the age band are domain ratings that show your child’s domain score is not yet similar to other children of the same age (not at age expectations).
  • A child who is younger than other children in the same age range may have domain ratings at the lower end of the age band. A child at the older end of an age range may have domain ratings at the upper end of the age band.
