In April 2024, the National Academies of Sciences, Engineering, and Medicine released a major report on preschool curriculum quality, the result of an extensive review led by a committee of early childhood experts.
For parents trying to evaluate a program beyond surface impressions, this research offers a genuinely useful framework.

Why This Report Matters
Most preschool marketing describes curriculum in vague, positive terms. This research gives parents something more concrete to evaluate against.
A Comprehensive, Evidence-Based Standard
The report synthesises research specifically focused on children ages three to five, with particular attention to multilingual learners, children with disabilities, and children from a range of socioeconomic backgrounds.
It identifies 29 distinct elements of curriculum quality across domains including social-emotional learning, executive functioning, language and literacy, math, and science.
Moving Past a False Debate
One of the report's central conclusions rejects a debate that's dominated early childhood discussions for years: the idea that play and academics are opposing approaches.
The research instead calls for both/and thinking, arguing that these concepts need not be in conflict and that the strongest curricula deliberately weave them together.
Key Elements Worth Understanding
A few of the report's core findings are especially useful for parents comparing specific programs.
Concept-Centered, Not Topic-Centered Content
The report distinguishes between curricula built around superficial topics and those built around meaningful concepts. A unit on "clothes" teaches vocabulary.
A unit on "growth and change" builds a transferable framework a child can apply across many contexts: science, stories, and their own development.
Guided Play as a Specific Pedagogical Tool
Intentional play experiences, particularly guided play, show significant positive effects on learning when implemented well.
The report frames guided play specifically as play where a teacher subtly shapes the activity toward a developmental goal, joyful and child-led, but not without purpose.
Developmental Sequencing
Quality curricula sequence activities to match how skills actually develop within each domain, rather than presenting content in an arbitrary order disconnected from how children build understanding over time.
Questions This Research Suggests Parents Should Ask
Armed with this framework, a few specific questions become more useful than general ones.
- Does the curriculum promote joyful, engaged learning that responds to children's actual interests, rather than following a fixed script regardless of engagement?
- Does it include a genuine range of play experiences, with meaningful teacher guidance woven in?
- Does content build toward concepts children can apply broadly, rather than isolated facts?
- How does the school train teachers to implement this kind of curriculum consistently, since quality depends heavily on execution, not just the curriculum document itself?
What Quality Actually Requires Beyond the Document
The report is clear that a strong curriculum document alone isn't sufficient.
School leadership has to be actively involved in supporting teachers in implementing it well, and ongoing professional development matters as much as initial curriculum design.
Why Implementation Is the Harder Half
Two schools can use curricula built on the same research foundation and produce very different classroom experiences depending on how well teachers are trained, supported, and given time to execute it thoughtfully.
This is why touring a classroom in session, watching a curriculum in actual use, matters more than reading a curriculum's marketing description.
The Role of Ongoing Assessment
Quality curricula also build in ways to track whether children are actually progressing, not as standardised testing, but as regular, low-pressure observation that helps teachers adjust their approach for individual children who may need more support in a specific area.
Applying This Research to Your Own Search
Understanding what must a quality preschool incorporate according to this kind of national research gives parents a genuine standard to evaluate against, rather than trusting marketing language alone.
The gap between a curriculum that looks good on paper and one that's genuinely well-implemented in the classroom is exactly what a direct conversation with teachers and administrators during a tour is meant to reveal.
Curriculum quality isn't a single feature to check off a list. It's a combination of thoughtful design, consistent execution, and teachers equipped to bring it to life every single day.
How This Research Applies to Specific Domains
The report doesn't treat all subject areas identically, and its domain-specific guidance is worth understanding for parents with particular priorities.
Language and Literacy
Quality curricula build early literacy through rich, varied language exposure, conversation, storytelling, and exposure to books, rather than isolated letter-recognition drills disconnected from meaningful context.
The research points to vocabulary development occurring most effectively when it's embedded in engaging, real content rather than flashcard-style repetition.
Math and Science
Similarly, math and science content in a strong curriculum shows up through hands-on exploration, counting during play, observing how materials behave, rather than worksheet-based instruction.
This mirrors the broader guided-play principle: concepts introduced through genuine engagement stick better than content delivered passively.
Social-Emotional Learning and Executive Functioning
The report treats these as core academic domains, not supplementary extras.
Skills like self-regulation, cooperation, and sustained attention are given equal weight to literacy and math within a genuinely high-quality curriculum framework, reflecting a growing body of research on the close link between these skills and later academic success.
Why This Matters Beyond a Single School Year
A preschool curriculum built on these principles isn't just preparing a child for kindergarten specifically.
It's building a broader foundation, comfort with structured learning, confidence engaging with new concepts, and the social skills to function well in a group setting that shapes how a child approaches school for years afterwards.
Evaluating curriculum quality this closely during the preschool search is a genuine investment in that longer trajectory, not just the immediate year ahead.
