This chart comes from page 61 of the report Hand in Hand, Schools’ Embrace of AI Connected to Increased Risks to Students from the Center For Democracy & Technology.

Their methodology seems sound to me, though I’m no expert:

Online surveys of nationally representative samples of 1,030 9th- to 12th-grade students,
806 6th- to 12th-grade teachers, and 1,018 6th- to 12th-grade parents were fielded between
June and August 2025. Quotas were set to ensure that the data collected among students,
parents, and teachers was representative of their respective audiences nationwide, and
the data was weighted as needed to align nationally with key demographics. Sample sizes
among all audiences were sufficient for analyses within key subgroups, such as gender, race,
ethnicity, and sexual orientation. Any subgroup sample sizes that differ from the total sample
size are denoted throughout this report
