All students enrolled in a U.S.-based, regionally accredited college/university are encouraged to apply. Preference is typically given to current sophomores and juniors with a GPA of 3.2 or higher that have an interest in research-based graduate studies. Those chosen to participate in SPUR must be 18 years or older by the program start date. Applications must be submitted and complete prior to the application deadline. A complete application includes a submitted online application, two letters of recommendation and official transcript(s). The letters of recommendation must be written by current and/or former professors/instructors or advisors, and should convey the applicant's interest in the sciences and research. Transcripts must be received from any current or previously attended college/university. The online application requires applicants to preference their three top areas of research interest. The areas available to choose from are representative of the areas that have traditionally hosted SPUR participants. Faculty will review applications primarily based around the research areas that applicants preference. It is the faculty who choose who they want to host as part of the program. Previous laboratory experience is preferred but not required. Participants will need to adjust accordingly to working in various laboratory settings.
