Admission into the 6th grade is based on an entrance exam consisting of one page of mathematics problems and an essay. For admission into the 9th grade, students must follow the DOE high school admissions process. As of 2013, admissions requirements for the high school are a minimum of 85% in all 7th grade classes and a grade of 3 to 4 (or a score of 650) in the
7th grade reading and math exams. Admission into both the 6th and 9th grades is competitive, with 3000 students applying for 190 places in the 6th grade and with approximately 3000 students applying for 136 places in the 9th grade. Lab Middle and Lab High are two discrete schools, and students who are accepted to Lab Middle School are not automatically admitted to Lab high school. Lab high school gives priority to applicants from district 2. ==Principals==
