Orianne Luo, Ziying He, Anusha Zaman (from left) are the three latest students at Baton Rouge Magnet High School students to earn perfect scores of 36 on the ACT college placement exam. They are among seven in the previous year at the high school to score so high.

Three more students at Baton Rouge Magnet High School have achieved perfect scores of 36 on the ACT, bringing to seven the number of students at the school during the previous year who earned this rare achievement.

Ed Colby, a spokesman for the Iowa-based ACT Inc., the publisher of the popular college placement exam, said only one-tenth of 1 percent of the 2 million students across the country taking the test score that high. In Louisiana the rate is half that. In the class of 2017, only 29 of the state’s 55,614 graduating seniors earned a perfect 36.

Colby said these scores are not a matter of chance. “These students have done extremely well in their classes and have done what they need to do well in college.”

The three latest students at Baton Rouge Magnet High to earn 36 on the ACT are Ziying He, Orianne Luo and Anusha Zaman. He and Luo are seniors; Zaman is a junior.

Their four fellow students who previously scored that high are Priya Balamurugan, Riley Devall, Marie Neubrander and Brian Tsai. Balamurugan and Devall are seniors, Tsai is a junior and Neubrander graduated in May.

Baton Rouge Magnet High, at 2825 Government St., is a selective school; students are admitted only if they have a GPA of 2.5 or better and they score on grade level or better on a standardized test. The school draws from across East Baton Rouge Parish, except for Baker, Central and Zachary, which have their own school districts.

Twenty-one of the high school's students have earned 36s on the ACT since 2012.

Shaun Feinberg, an assistant principal at the school, said every junior and senior takes the ACT every March, about 700 students each year, and many of them take it again on other test days.

The average ACT score nationwide is 21 and in Louisiana is 19.6. That’s a composite of the result of four tests in four subjects: English, math, reading and science.

Due to rounding, a student who earns a composite score of 36 did not necessarily get every question right, but they almost did, Colby said.

“They might have gotten one wrong,” he allowed.
