The Early Childhood Classroom Observation Measure was used to observe 91 first-grade and 70 third-grade teachers in Estonia and Finland. Using a person-oriented approach, four profiles of teaching practices were identified in grade 1: the child-centred style, teacher-directed style, child-dominated style and a mixture of the child-centred and teacher-directed styles. An additional profile, the extreme-child-centred style, was found in grade 3. Children taught by child-centred teachers showed the highest reading skills, whereas children taught by child-dominated teachers showed the lowest skills. More Estonian than Finnish teachers applied the child-dominated style in grade 1 and the extreme-child-centred style in grade 3.
