Teacher-family partnerships are crucial elements of high-quality early childhood education. The factors influencing these partnerships, particularly for children under age 3, are not well known. This study compares teachers' and mothers' perspectives on their partnership and the ideal practices they would like to see implemented. Additionally, it investigates child, family, and program-level factors predictive of partnership practices. Participants were mothers and teachers of 90 infants who completed the Real-Ideal Teacher-parents Partnership Scale; mothers rated child's temperament, and classroom quality was observed 6-months after infants entered childcare. Home environment was assessed before infants entered childcare. Both mothers and teachers reported a medium-high number of practices being implemented, but ideally, would like more practices to be implemented. The frequency of mother and teacher reports of real and ideal practices were significantly associated, although teacher reports were higher. Findings from the regression analyses showed that teacher level of education (having a Master) was uniquely and positively associated with both teachers' and mothers' reports of real partnership practices, and was significantly associated with teachers' reports of ideal partnership practices. Mothers' education level predicted their ideal partnership practices. Findings highlight the importance of teacher education for partnerships, especially considering the variability in legal requirements regarding qualifications for teaching infants across Europe.
