Prenatal alcohol exposure causes preventable disability

Prenatal alcohol exposure causes a dose-related spectrum of neurodevelopmental harm — lowered IQ and deficits in learning and memory, executive function, and attention regulation, with or without facial dysmorphology — and is a leading preventable cause of developmental disability; no safe level of alcohol use during pregnancy has been established.

instruction, resources & composition

Systematic phonics is essential to early reading

Systematic phonics instruction — explicitly teaching grapheme-phoneme correspondences in a defined sequence — improves early reading, especially decoding and word reading, with the largest benefits for younger children and for students at risk for or with reading disability; it is an essential component of effective beginning reading instruction.

Nurse home visiting works best for the highest-risk families

Nurse home-visiting programs — notably the Nurse-Family Partnership — produced lasting benefits in replicated randomized trials, especially for higher-risk subgroups (such as children of mothers with low psychological resources and reduced offending among girls), but several large-scale and international replications found null effects on their primary outcomes, so at-scale effectiveness is more modest and uneven.
