What Is Developmentally Appropriate Practice (DAP)? A Teacher's Guide

Developmentally appropriate practice — DAP for short — is NAEYC's framework for teaching that fits how children develop and learn.

NAEYC, the National Association for the Education of Young Children, published DAP as a position statement: it says each child from birth through age 8 has the right to equitable learning opportunities, in centers, family child care homes or schools.

For a teacher, DAP answers a question you face every day: does this activity, this room setup, this response to behavior fit the children in front of me?

The answer weighs three things — what children that age share, what makes each child in your room different, and the setting you are teaching in.

Those are the core considerations the next section covers.

The framework lives in two documents.

The position statement, copyright 2020, states it; the companion book — 'Developmentally Appropriate Practice in Early Childhood Programs Serving Children from Birth Through Age 8' — is in its fourth edition.

DAP language follows you from teacher training into interviews, evaluations and curriculum work.

DAP is the teaching side of the daycare teacher career guide's subject: the role itself — duties, age groups, requirements and pay — is covered there.

NAEYC names three core considerations in DAP: commonality in children's development and learning, individuality reflecting each child's unique characteristics and experiences, and the context in which development and learning occur.

In DAP the three are weighed together — they are questions to keep asking, not a checklist to clear once.

• Commonality — the development and learning children share. It is the knowledge that lets a teacher expect certain patterns at a given age and plan for them: a room of infants needs a fundamentally different day than a pre-K group.
• Individuality — each child's unique characteristics and experiences: temperament, family culture, home language, strengths, pace of development, or a disability or delay. Two children the same age can need different supports, and adjusting for that is what this consideration asks of the teacher.
• Context — everything surrounding development and learning: the family, the community, the culture, and the program itself. A schedule that fits one program's families may not fit the next one's, which is why DAP decisions do not transfer between rooms unchanged.

In practice the three interact.

Age-level knowledge sets the frame, individual knowledge adjusts it, and context decides how a plan actually lands — a circle time that suits a preschool group's commonality can still be wrong for one child in it, or for a program whose families drop off across a long window each morning.

Anti-bias education, a framework from Derman-Sparks and Olsen Edwards, adds four core goals for that individuality-and-context work: identity, diversity, justice and activism.

The same framework produces different rooms at different ages, because what children share changes fast across early childhood.

These are the shapes DAP takes in the age bands centers hire for.

• Infant rooms. Think responsive caregiving. Harvard's Center on the Developing Child calls the back-and-forth between a young child and a caring adult 'serve and return' — responsive exchanges that it says play a key role in shaping brain architecture. In an infant room that is the teacher noticing a babble, a gesture or a gaze and answering it, over and over, inside feeding, diapering and play. At this age care and teaching are the same work: a diaper change narrated back and forth is a language lesson.
• Toddler rooms. DAP looks like movement and choice: hands-on materials instead of long stretches of sitting, short and flexible group gatherings, and choices inside predictable limits — 'red cup or blue cup?' Teachers coach emerging skills (words, walking, self-feeding) by narrating and modeling rather than doing it for the child, and they redirect behavior instead of lecturing.
• Preschool rooms. Play carries the academics. One published example: Teaching Strategies describes The Creative Curriculum for Preschool as a curriculum for 3- and 4-year-olds built on play-based studies. A developmentally appropriate preschool day holds long blocks of child-directed play, small-group times, and early literacy and math woven into real activity: counting at snack, letters in the writing corner, a teacher extending block play with open-ended questions.

Across all three rooms the teacher's move is the same: watch the children, weigh commonality, individuality and context, then set up the shelves, the schedule and your responses to fit what you saw.

The age band changes the content; the reasoning does not change.

DAP gets miscast in both directions — as permissive, or as a product you can buy — and the distinctions can come up in interviews and coaching conversations.

It is not a curriculum. You cannot buy DAP off a shelf.

Curricula are the published materials a program adopts — Teaching Strategies describes The Creative Curriculum for Preschool as one such curriculum, for 3- and 4-year-olds.

DAP is the professional judgment layer: how you use whatever curriculum your room is given, with the children actually in it.

It is not a behavior program. The Pyramid Model — a framework of evidence-based practices for promoting young children's social-emotional development — is a separate tool, and even its developers describe it as not a curriculum: it works alongside a program's curriculum.

A center can run DAP, the Pyramid Model and a published curriculum at once; they answer different questions.

It is not 'children do whatever they want.' Commonality is one of the three core considerations: teachers still hold age-level expectations, plan intentionally, and teach skills directly.

Play is the method, not the absence of a plan — and early academics belong in DAP when they are taught in ways the age can actually use.

It is not a licensing rule, and it is not the NAEYC ethics code. A position statement is professional guidance, not law.

The requirements that bind your classroom — staffing, training, qualifications — come from your state child care licensing agency, and some state rules do name DAP as a training topic: Kentucky's orientation for staff with supervisory authority and Indiana's annual in-service for center directors must cover developmentally appropriate practice.

And NAEYC's code of ethics, which covers educators working with children from birth through age 8 in all early childhood settings, is a separate document about professional conduct, not teaching decisions.

Interviewing for daycare teacher jobs, you may hear questions that are DAP questions in disguise: what would you put on the shelves for toddlers, how would you run circle time for a wiggly group, tell me about a time a child's behavior challenged you, how do you communicate with families?

The interviewer is listening for whether you adjust to the age group and the individual, or whether you have one fixed script.

The strongest answers say the three considerations out loud: what children that age share, what this particular child brings, and what the setting and family context add.

Naming the reasoning turns an activity answer into a practice answer — and it is the same habit to bring to coaching conversations and evaluations once you are hired.

Child assessment tools run on the same logic.

Teaching Strategies describes GOLD as an online observational assessment for children from birth through third grade, rated against research-based objectives — Teaching Strategies cites 38 of them — and its checkpoint reports show which children are below, at or above widely held expectations.

If your program uses GOLD, the daily observations you are already writing are the raw material for it.

Classroom-quality observations can use published environment rating scales, which come in an edition per setting: ECERS-3 (2015) for center-based programs serving ages 3 to 5, ITERS-3 (2017) for center-based programs birth through age 2, FCCERS-3 (2019) for home-based programs birth through age 12, and SACERS-U (2014) for school-age care ages 5 to 12.

An observer scoring your room with one of these is rating the environment you built — materials, schedule, interactions — which is exactly the ground DAP decisions shape.

Prepare for interviews and evaluations the same way: be ready to explain the why behind your room setup, your planning and your responses to behavior in terms of age, individual children and context.

That is the habit DAP builds.
