What is the average high school GPA to get into Lowell school?

There's no publicly released average GPA for students admitted to Lowell High School. Lowell, like many highly selective schools, doesn't publish this specific statistic. Admission is holistic and based on a complex formula considering many factors beyond GPA, including test scores (though these are currently not considered), grades in specific subjects, and extracurricular activities. While a very high GPA is certainly necessary, it's not the sole determinant of acceptance.
