Public school pre-K linked to lasting academic advantage in large US study

Children who attended public school pre-K recorded stronger academic results than those who experienced other forms of early childhood care, with a large US study finding differences that persisted through high school.

Children’s early learning environments may be associated with academic outcomes well beyond the transition to school, according to research drawing on data from around 400,000 students.

The research examined the educational trajectories of children attending Miami-Dade County public schools in Florida, comparing outcomes according to the type of early childhood program children attended before starting elementary school.

Researchers found children who attended public school pre-kindergarten (pre-K) subsequently achieved higher grades and standardised test scores than children who had attended other forms of early childhood care, with differences continuing into adolescence.

The findings have also drawn attention to characteristics that differed between the early childhood settings examined, including teacher qualifications and the structure of children’s learning experiences.

The research involved around 400,000 Miami-Dade County public school students and drew on approximately 20 years of data.

Researchers compared children who had experienced three types of early childhood provision before entering elementary school: public school pre-K, centre-based programs and home-based providers participating in the local Early Learning Coalition.

All three forms of provision were required to meet minimum standards, but there were differences between the settings that could potentially contribute to children’s subsequent outcomes.

One of the most notable involved teacher preparation.

Public school pre-K was the only setting examined where teachers were required to hold a college degree.

Florida International University Associate Professor of Teaching and Learning Charles Bleiker said this difference could be important when considering the stronger academic outcomes associated with public school pre-K.

“They had more education and probably higher-quality teachers,” Associate Professor Bleiker said.

The researchers suggested educators with greater preparation in areas such as child development and classroom management may be better equipped to respond to children’s learning and behavioural needs.

However, the research does not establish that teacher qualifications caused the differences in children’s subsequent academic achievement.

Other characteristics of the programs, as well as children’s family circumstances and subsequent educational experiences, could also contribute to the results.

Students who had attended public school pre-K subsequently recorded higher grades and standardised test scores than children who had experienced other forms of early childhood care.

According to the researchers, those differences remained evident as students progressed through school and into adolescence.

The findings are significant because questions about the longer-term effects of early childhood education have often centred on whether initial advantages persist once children enter formal schooling.

In this population, the researchers found differences associated with children’s preschool experiences remained evident much later in their education.

The results are observational, however, and should not be interpreted as demonstrating that attendance at public school pre-K directly caused stronger academic performance.

Teacher qualifications were not the only possible explanation considered by researchers.

Associate Professor Bleiker suggested children attending pre-K within a public school environment may also become familiar with routines and expectations similar to those they subsequently encounter at elementary school.

Curriculum and other characteristics of children’s learning environments could also contribute to differences between settings.

The quality of children’s subsequent schooling was another important consideration.

The research therefore highlights the importance of looking at children’s education as a continuum, rather than attempting to separate the influence of preschool from the experiences children have once they enter school.

The researchers did not conclude that early childhood education should necessarily be delivered through public schools.

Instead, Associate Professor Bleiker suggested identifying characteristics associated with stronger outcomes in public school pre-K could help inform improvements in other forms of early childhood provision.

This distinction is important.

The study does not establish that school-based pre-K is inherently superior to centre-based or home-based provision.

Instead, the findings raise questions about which characteristics, including teacher preparation, curriculum, learning environments and continuity between early childhood and school, may contribute to longer-term outcomes.

The research was conducted in the United States and did not examine Australian children, educators or early childhood education and care (ECEC) services.

Differences between the US and Australian systems mean the findings cannot be directly applied to Australian ECEC.

However, the research is relevant to continuing Australian discussions about teacher and educator qualifications, professional preparation and the characteristics of high-quality early learning environments.

In Australia, qualification requirements differ according to educators’ roles and the type and size of the service, with the National Quality Framework establishing requirements for appropriately qualified educators and early childhood teachers.

Against that backdrop, the US findings provide an additional perspective on the relationship between professional preparation and children’s longer-term educational experiences – while stopping short of demonstrating that qualifications alone produce better outcomes.

For Australian approved providers and policymakers, the research also reinforces the value of considering not simply whether children participate in early learning, but which characteristics of their early learning environments may be associated with benefits that persist as they progress through school.

Much of the discussion about the benefits of early childhood education focuses on children’s development and their transition into formal schooling.

This research provides a longer-term perspective.

Its findings suggest differences associated with children’s early learning experiences can remain visible years later, while also demonstrating the importance of considering the quality of the schooling children subsequently receive.

For the ECEC sector, that creates a broader question: which characteristics of high-quality early childhood provision are most likely to support positive outcomes that endure as children progress through school?

The research does not provide a single answer. However, it places teacher preparation, curriculum, learning environments and continuity across children’s educational experiences firmly within that discussion.
