Our findings suggest that the program has no effects on the reading or math achievement of
non‐disadvantaged gifted students, who must meet a 130 point IQ standard to achieve traditional gifted
status. Nor does it affect the reading or math scores of disadvantaged gifted students (free/reduced
price lunch participants and English language learners) who face a lower 116 point IQ threshold for "Plan
B" gifted status. However, it has positive and relatively large effects on the achievement of the nongifted
high achievers who fill the remaining seats in the class, concentrated among free/reduced price
lunch participants and black and Hispanic students.
