If you are academically curious, excited about learning, and thrive in cooperative work environments, SLAI is the program for you!
At SLAI, you will connect with like-minded peers from all over the nation and world, all while earning college credit and learning from top-ranked Carleton faculty, who are experts in their field. Choose from 6 programs, with topics in: History, Literature, Storytelling, Sociology, STEM, Computer Science and Neuroscience.
Students who attend SLAI come away from the program on April 6 with improved college-level reading, writing, and research skills, an increased knowledge of topics and majors they may want to study in the future, and a general sense of preparedness for college.
During the program, students spend their mornings and afternoons in class, conducting research, and in hands-on labs. Specially, a variety of social activities are available after class every day, from frisbeeto beading to making models. Weekend field trips to attractions in surrounding cities are also included in the program. Past destinations have included amusement parks, museums, or even a day at the lake!
