A RAND research brief summarising the Portland immersion lottery study for a policy audience. No new analysis.
Key findings
Restates the Portland lottery findings. Recorded so that the popular-summary version of the result is on file next to the study, and specifically so that its headline - which names English achievement and says nothing about second-language proficiency - is visible as the source of the public claim.
Genetic confound
Not applicable.
