Long-View Micro School, a private school serving second-through-fifth-grade students, has expanded ahead of its 2016-17 school year.

The school serves between 20 and 24 students this year, bringing on two cohorts of between 10 and 12 students.

Long-View—located near the University of Texas campus at 1201 W. 24th St., Austin—grew out of mathematics programs The Number Lab and focuses on STEM, or science, technology, engineering and math, education. Its five core academic areas are math, science, computer science, reading and writing.

“We are seeking to reimagine what school looks like and feels like,” co-founder Lisa Zapalac said.

Although children Long-View admits are those entering second through fifth grades, there are no grade levels at the school, one of the main traits of micro schools, which have been opening throughout the U.S, according to the school. Among the micro school’s tenets are small student cohorts, personal connections, teacher empowerment and unique curriculum, according to its website.

Renovation work at the school this year included adjoining several small offices to create a larger, multipurpose classroom and adding instructional lab spaces and an additional office/work room.

Annual tuition is $9,500 with a $500 registration fee.

Long-View’s classroom environment does not have amenities one would expect to find in a traditional school. There are no desks or chairs; students sit on couches. Long-View’s pupils do not work on worksheets but instead discuss their thoughts and work together to solve problems, the school said.

Classes are held Monday through Thursday from 9 a.m.-2:30 p.m. No class on Friday allows the children to spend time with their family, learn fine arts, or engage in other interests, the school said.
