Admissions and enrollment Prior to 2012 Because of the limited enrollment, before 2012 students were chosen from applicants from Lake Washington School District's 7th grade class by lottery, and there were limited opportunities for transfer into higher grades after being put on a waitlist. After the school district moved from a K-6 elementary school system to a standard K-5 elementary school in Fall 2012, which changed the admissions of ICS to be in 6th grade. The school has a grandfather clause allowing for students who are members of founding families or who had sibling in the first class of the school to be admitted without going through the lottery system. Introduction of 6th graders Beginning from the 2013-2014 school year and coinciding with the larger change among the school district, 6th graders were given admission to ICS. The application process and lottery were moved upward for 5th graders, and the waitlist process remained the same. There are currently only about 30 of the original students from the first 6th grade class left (there were originally over 60). They were the first ones to go to a 6th grade day camp. The same year ICS introduced a 6th grade class, a time capsule was made and was set to be opened 100 years later. Demographics As of 2020-21, ICS had an enrollment of 429 students, with minorities consisting of 47% of the total student body. The total demographic of the school can be broken down into the following: 36% Caucasian 54% Asian 3% Hispanic 0% Pacific-Islander 6% Two or More Races The ratio of male students to female students is 48:52. Academics The school has a student-teacher ratio of 18.76, with 19 full-time teachers, and has a 98% graduation rate. Focus Week Every May, ICS sends its students outside the classroom environment for a week to "explore concepts outside those normally encountered in schools". Students select the Focus Week that they have interest in and are placed in a small group to meet with throughout the school year. Each group is assigned a faculty adviser who helps plan, organize, and schedule the itinerary for the week-long education experience. Focus Weeks this year include international trips to Greece, Japan, the Netherlands, and Iceland, domestic trips including New York and The Grand Canyon, and local trips, such as Circus Arts, Teacher's Assistants, Seattle International Film Festival, and Blue Ribbon Cooking.
