the four day care patterns investigated were Low quality (0-3) Low quality (3-5), Low quality (0-3) High quality (3-5), High quality (0-3) Low quality (3-5) and High quality (0-3) High quality (3-5).
The results found that High-high children will have better outcomes than low-high children, for all areas maths, reading and language.
Results found High-low children will begin preschool with better outcomes than low-low, but their advantage will be eliminated in low-quality preschool. High-low children were better at the start.
