Evidence Based Strategy
Quality Improvement Systems are a cornerstone strategy for advancing kindergarten readiness by ensuring that early childhood education (ECE) programs provide consistent, high-quality experiences. Because research demonstrates that high-quality early learning environments have lasting impacts on cognitive, social-emotional, and academic outcomes, quality improvement systems are designed to set and enforce standards, build capacity, and promote a culture of continuous learning within the early childhood sector.
At their core, quality improvement systems integrate multiple mechanisms including standards, ratings, coaching, grants, and family engagement to help ECE providers move from compliance toward excellence. They create a clear pathway for providers to understand expectations, measure progress, and access supports needed to strengthen practice. Importantly, quality improvement systems are not only about compliance or accountability; they are about embedding continuous quality improvement (CQI) into the DNA of early learning systems.
Kindergarten readiness is shaped by many factors like exposure to developmentally appropriate curriculum, high-quality teacher-child interactions, supportive family engagement, and effective program administration. Quality improvement systems address each of these elements systematically. Through tools such as Quality Rating and Improvement Systems (QRIS), programs can benchmark their current level, identify gaps, and access resources like professional development or technical assistance to move to higher tiers of quality. This tiered approach incentivizes progress while giving families transparent information about program quality.
For children, the impact is direct: programs engaged in quality improvement systems typically demonstrate stronger teacher-child interactions, better-prepared educators, improved learning environments, and greater family involvement. These, in turn, are linked to improved early literacy, numeracy, socio-emotional skills, and executive functioning which are all key predictors of kindergarten readiness.
Quality improvement systems matter because they move the entire early care and education ecosystem toward higher quality. Rather than relying on a patchwork of individual program efforts, quality improvement systems provide a statewide or community-wide framework that aligns expectations, ensures accountability, and supports improvement. This systemic approach reduces disparities, raises the floor for quality, and creates conditions where all children can enter kindergarten ready to thrive.
Research consistently demonstrates that high-quality early learning experiences yield lasting benefits for children’s academic and social development, and quality improvement systems are one of the most effective mechanisms for ensuring quality at scale. Studies from the Learning Policy Institute show that when early childhood education programs meet clear quality standards such as staff qualifications, curriculum alignment, and appropriate child-staff ratios children enter kindergarten with stronger language, literacy, and math skills. These gains not only persist into elementary school but also reduce achievement gaps for children from low-income families.
Evidence from states that have implemented Quality Rating and Improvement Systems (QRIS) further supports the role of quality improvement systems in advancing child outcomes. Evaluations in North Carolina, Pennsylvania, and Colorado found that programs with higher QRIS ratings demonstrated stronger teacher-child interactions, better classroom environments, and more consistent use of evidence-based practices. Importantly, children enrolled in higher-rated programs showed improved outcomes at kindergarten entry, including enhanced early literacy and socio-emotional development. These findings suggest that transparent rating systems not only drive provider improvement but also give families critical information to select quality care.
Another key element of quality improvement systems is professional development and coaching, which research shows are essential for improving educator practice. The Institute of Medicine and National Research Council emphasize that a highly skilled workforce is the most important factor in delivering high-quality early learning. Programs that embed coaching, mentoring, and practice-based professional development into their improvement frameworks see more effective teacher-child interactions and stronger gains in children’s readiness skills.
Finally, the inclusion of family engagement within quality improvement systems is supported by a robust body of evidence linking parent involvement to positive child outcomes. Research from the U.S. Department of Health and Human Services and Head Start finds that programs with strong family engagement practices foster better attendance, stronger family-school connections, and improved readiness outcomes for children. Programs rated highly in family engagement indicators not only benefit children directly but also strengthen the broader partnership between families and educators.
Taken together, this body of research confirms that quality improvement systems are not abstract policy tools but proven levers for improving the quality of early childhood education. By embedding standards, providing resources for professional growth, offering transparent ratings, and engaging families, quality improvement systems create the systemic conditions necessary for children to enter kindergarten prepared for success.
For quality improvement systems to succeed in improving kindergarten readiness, several enabling conditions must be in place:
Clear, Aligned Standards
Sustainable Funding
Workforce Supports
Accessible Technical Assistance
Data Systems and Continuous Learning
Family and Community Engagement
Political and Provider Buy-In
Track both early signals and long-term outcomes.
Quality in early care and education (ECE) is a leading indicator of kindergarten readiness because children benefit most when their early learning experiences go beyond basic health and safety to provide rich, developmentally appropriate instruction and support. High-quality ECE fosters stronger cognitive, social-emotional, and language skills, which are critical for school success.
Quality encompasses multiple dimensions, including nurturing educator-child relationships, evidence-based curricula, and well-prepared, professionally supported educators. In Kentucky, the KY ALL STARS Quality Rating and Improvement System evaluates these dimensions across four domains: classroom and instructional quality, staff qualifications and professional development, family and community engagement, and administrative and leadership practices. Higher ratings reflect alignment with Kentucky’s Early Childhood Standards, strong family partnerships, continuous improvement systems, and robust educator supports.
In 2023, fewer than half of Kentucky’s licensed and regulated ECE providers were rated high-quality (3 stars or higher), with a statewide average of 2.7 stars. Indicators used to track quality include the percentage of high-quality providers, the share of communities with average ratings of 3 or better, the proportion of early childhood slots in high-quality settings, staff-to-child ratios, and health and wellness referrals. Improving these metrics strengthens early learning environments and better equips children for success in kindergarten and beyond.
A high-quality early care and education (ECE) workforce is a cornerstone of kindergarten readiness. Skilled, well-supported educators create nurturing, engaging, and developmentally appropriate environments that foster children’s cognitive, social-emotional, and physical growth. Key components of a strong ECE workforce include formal education and ongoing professional training, recognized credentials and career pathways, deep knowledge of child development, cultural competence, and the ability to build strong relationships with children and families. Educators must also demonstrate socio-emotional competence, uphold high health and safety standards, and engage in advocacy and leadership for the profession.
Investing in the ECE workforce through professional development, scholarships, competitive compensation, and supportive working conditions helps recruit and retain talented educators committed to children’s success. In turn, children benefit from consistent, high-quality interactions that build the skills needed for school and life.
Kentucky tracks workforce quality through indicators such as the number of ECE-specific degrees and credentials earned, the number of scholarships awarded to educators and directors, the number of teacher leads and assistants, staff turnover rates, and the proportion of early educators trained in early literacy. Strengthening these metrics ensures that more children enter kindergarten with a solid foundation for learning, setting them on a path toward lifelong achievement.
Third grade proficiency in reading and math is a critical lagging indicator for kindergarten readiness, reflecting the long-term impact of early learning experiences on academic achievement. Students who enter kindergarten ready to learn are significantly more likely to reach proficiency or higher on third grade state assessments. In Kentucky, data from the Brigance Kindergarten Screener shows a strong correlation: children rated as “ready” or “ready with enrichments” in kindergarten consistently outperform their peers in third grade reading and math, while those not ready are more likely to score at the novice or apprentice levels.
This relationship matters because third grade marks a pivotal shift from “learning to read” to “reading to learn,” a transition that affects success across all subjects. Proficiency at this stage predicts future academic achievement, including middle and high school performance, graduation rates, and postsecondary readiness. Conversely, children who are not proficient by third grade face increased risks of grade retention, remedial coursework, and lower educational attainment.
As a lagging indicator, third grade proficiency captures the cumulative effects of children’s early environments, access to quality early care and education, and kindergarten readiness. It is an essential measure for evaluating the effectiveness of early childhood investments and identifying where supports are needed.
