Summary

Adelante Selby Spanish Immersion is a K–5 Spanish immersion school in Atherton, serving 582 students in the Redwood City Elementary district. SchoolDigger places the district at the 48th percentile statewide, while the school is at the 59th percentile. In 2025–26, about half of students were proficient in ELA, 41% in math, and 36% in science—just above state results in all three subjects, but below district results in each. The most important concern is fifth-grade math: 23% were proficient, compared with 37% statewide and 37% in the district.

Compared with four nearby K–5 schools in the same district, Adelante’s all-grade results were higher than their average in each subject, especially science: 36% versus 27%; ELA was 50% versus 41%, and math was 41% versus 40%. Math is its clearest strength against the state, where it was about 3 percentage points higher, while its ELA and science results were essentially level with state results. The district was ahead of Adelante in all three subjects. Fifth-grade results show a sharper contrast: math proficiency was below Orion Alternative, Roy Cloud Elementary, and Henry Ford Elementary, while fifth-grade ELA and science were above state results.

Math has improved most over time, rising 8 percentage points from 2022–23 to 2025–26 and moving from below to above the state result; ELA gained 1 point, while science ended 1 point below its earlier result. Chronic absenteeism also fell, from 29% in 2021–22 to 10% in 2025–26. SchoolDigger gives Adelante 3 stars; its 59th-percentile standing is mid-range among seven district schools with rankings, behind Orion, Roy Cloud, and Henry Ford. The student-teacher ratio was 25.3 in 2024–25, and 60% of students were reported as free/reduced lunch eligible that year. SchoolDigger’s 2024–25 ranking for White Students was at the 100th percentile, compared with the school’s overall 59th percentile; for Disabled Students, its 2021–22 ranking was at the 16th percentile, compared with the overall 42nd percentile. These subgroup rankings each represent only one reported year, so they do not establish a lasting pattern.
