How big are Leander ISD's classes?

In short

• Grade school classes have about 17 to 20 students. That is a bit below the state in each grade.¹
• Middle and high school core classes have about 21 to 23 students. The state has about 16 to 19.¹
• These classes are the largest of six nearby districts.¹²

How it works

• The state reports average class sizes for each grade in elementary school and each core subject in middle and high school.¹
• The numbers come from teacher records. They are averages, so some classes are bigger and some smaller.³
• State law limits classes from pre-K to grade 4 to 22 students. There are a few exceptions, and a district can ask the state for a waiver.⁴

Source: Texas Education Agency, 2024-25 school report for each district, average class size.¹²

• Leander has the smallest kindergarten and grade 3 classes of these districts.¹²
• In middle and high school, Leander’s classes are the largest in English, math, science and social studies.¹²
• Grade 6 classes are the second largest, after Liberty Hill.¹²

The other side

• Averages hide a lot. Electives, advanced classes and special education classes can be much smaller or larger.
• Secondary class sizes depend on schedules. How many periods teachers teach and how many electives a school offers change the average.
• Class size is not the same as students per teacher. Leander has the fewest students per teacher of six nearby districts on another page, which uses a different list of districts. See spending per student nearby.

Changes to this page

• Nov. 2, 2026: Rewrote the questions to ask so each is open, neutral and addressed to the public body.
• Nov. 2, 2026: The class-size limit covers pre-K as well as kindergarten to grade 4. We fixed that and now cite the official text of the law.
• Nov. 2, 2026: We checked every figure against its source. We reworded the other-side points so they stick to what the sources show.

Questions to ask

• How does the district explain its secondary core class sizes compared with nearby districts?
• How many elementary classes went over the state limit, and did the district ask for waivers?

What we still don’t know

• Class sizes at each school. This page uses district averages only.
• Whether these sizes have grown over time. Older reports use a different layout, and we did not compare them.
