Age-appropriate vs developmentally appropriate goals and materials

By the IEP Atlas editorial teamLast updated November 1, 2026

Short answer

Developmentally appropriate describes the skill level a student is ready to learn next. Age-appropriate describes the materials, activities and settings that fit the student's actual age. Strong IEPs use both: teach the next skill on the student's developmental path, using materials and contexts a same-age peer would use. Ask: would a classmate this age use this material?

The two terms get used as if one cancels the other. A team says a 14-year-old is "developmentally at a preschool level," so the goal targets counting to 5 with farm animal counters and a toddler song. The skill may be right. The materials and context are not. The student is 14.

The working answer is to split the question. What to teach comes from the student's present skills: that is the developmentally appropriate part. How and where to teach it comes from the student's age: that is the age-appropriate part. A 14-year-old can count to 5 by counting dollar bills, team jerseys or items on a grocery list.

This matters most for students with significant support needs. The pillar on IEP goals for students with severe and profound disabilities lists age-respectful materials as one of its core principles; this page shows how to apply it.

The deciding question

Ask: would a classmate of the same age, without a disability, use this material or do this activity in this setting?

If yes, the material or activity is age-appropriate.
If no, keep the skill and change the material or context.

The question applies to materials, activities and settings. It does not apply to the skill itself. A skill is chosen from data on what the student does now and what comes next.

Side-by-side comparison

	Developmentally appropriate	Age-appropriate
What it describes	The skill level the student is ready to learn next	Materials, activities and settings that fit the student's chronological age
Where it comes from	Present levels, assessment data, skill sequences	The student's age and what same-age peers do
Basis in law or practice	Early childhood practice uses the term for instruction matched to a child's development^[3]	IDEA refers to age-appropriate regular classrooms^[1] and age-appropriate transition assessments^[2]
Who decides	The IEP team, from data	The IEP team, using the same-age peer test
Example for a 15-year-old	Count sets to 10	Count change at a school store, not counting bears
Where it shows up in the IEP	Present levels, annual goals, objectives	Goal conditions, materials, settings, transition plan
Risk if used alone	Childlike materials and settings that isolate the student	Grade-level tasks with no path to the skill
How it is measured	Progress on the target skill	Whether the context matches peers (setting, materials)

Examples by area

Area	Skill (developmental)	Not age-appropriate for a teen	Age-appropriate for a teen
Reading	Match 10 sight words	Picture books for toddlers, alphabet songs	Community signs, menus, a sports page with adapted text
Math	Count to 10	Counting bears, nursery rhymes	Counting bills, items on a shopping list, reps at the gym
Communication	Request with 2-symbol messages	Symbols for "bottle" and "nap"	Symbols for music apps, snacks, friends' names
Leisure	Take turns	Toddler shape sorters	Card games, video games, music playlists
Fine motor	Grasp and release	Pegboards with cartoon pegs	Sorting recyclables, stocking shelves, assembling packets
Self-care	Wash face	Cartoon soap, baby wipes	Teen face wash, a mirror at the right height

Goal templates written this way are on the significant support needs goal page.

Three classroom scenarios

Scenario 1: the counting goal. A 13-year-old counts objects to 3 with one-to-one correspondence. The draft goal reads: "Using counting bears, the student will count to 5." Answer: keep the skill, change the material. "Given up to 5 items during a class snack job, the student will count out the correct number of cups for the group on 4 of 5 days." Why: the skill target is unchanged, and the context is something peers see as a real job.

Scenario 2: the leisure choice. A 16-year-old with extensive support needs chooses a toddler musical toy at free time every day. Answer: respect the preference and widen the options. Offer teen alternatives that give the same sensory feedback, such as a music app with large buttons or a drum pad, and let the student choose. Why: the student's preference is real information. Age-appropriate does not mean removing choices; it means offering choices that also fit the student's age and peer group.

Scenario 3: the reading group. A 4th grader reads at an early level and is placed in a kindergarten room for reading. Answer: teach the early reading skills, but within the 4th grade setting when possible, with adapted grade-level texts and decodable passages that look like what classmates read. Why: placement in an age-appropriate classroom is the starting point under IDEA, and removal needs a reason beyond the need for modified curriculum.^[1] The TIES Center has resources on including students with significant cognitive disabilities in general education.^[4]

Writing goals that respect both

Pick the skill from data. Use present levels and a skill sequence. See present levels for students with severe disabilities.
Write the condition with age-appropriate materials. "Given a shopping list with 4 pictured items" instead of "given picture cards."
Choose a real setting. The cafeteria, the school store, a general education class, a community site.
Check generalization. A skill learned with toddler toys often stays with the toys. A skill learned with real materials is closer to use.
Use task analysis for routines so the steps are clear in the real setting.

When you need both

Every goal for a student with significant disabilities needs both. The developmental side keeps the goal reachable. The age-appropriate side keeps it respectful and useful. Most mistakes happen when a team looks at only one:

Only developmental: a 17-year-old sorting colored blocks. Reachable, but not useful at 17 and isolating in front of peers.
Only age: a 17-year-old asked to read a grade 11 text with no adaptation. Respectful in setting, but no path to learning.
Both: a 17-year-old sorting work supplies by color at a job site. Same skill, real use, adult context.

Before finalizing, read each goal and ask the deciding question about its materials and setting. Then paste it into the goal checker. For goals in daily living, see personal care participation IEP goals. For adult outcomes, see transition planning in the IEP.

Frequently asked questions

What is the difference between age-appropriate and developmentally appropriate?

Developmentally appropriate is about the skill: what the student is ready to learn next. Age-appropriate is about the context: materials, activities and settings that fit the student's real age. Good goals set the skill from data and the context from age.

Is it wrong to use preschool materials with an older student?

Usually it is better to keep the skill and change the material. A teen can practice counting with money or work supplies instead of counting bears. If a student strongly prefers a younger item, offer teen options that give similar feedback and let the student choose.

Where does age-appropriate appear in IDEA?

The regulations refer to age-appropriate regular classrooms in placement decisions and to age-appropriate transition assessments in the transition part of the IEP. Developmentally appropriate is a term from early childhood practice rather than IDEA itself.
