  • Redaction Requirement: Before uploading, you must remove (blank out, black out, make illegible) any Social Security numbers and/or full dates of birth (month, day, year). Applications containing this Personally Identifiable Information (PII) will be deemed non-compliant and will not be released to host laboratories or facilities for review or consideration. The application system provides an easy-to-use upload feature. The upload feature does provide a redaction tool to assist in redacting your PII from your transcript. It is your responsibility to ensure that your PII is redacted or removed from your transcript.

  • Eligibility-Specific Transcript Requirements:
    • Current/Recent Institution: Submit the most recent transcript available from your current or recently-graduated undergraduate institution. This transcript must have been printed or accessed no earlier than the application opening date.
    • Prior Institutions: Additionally, submit undergraduate transcripts from all other undergraduate academic institutions you attended as a matriculated postsecondary student within the 5 years preceding your current enrollment. This includes transcripts for any transfer credits earned from previously attended colleges/universities.

3. Two Letters of Support

Recommendations are submitted directly by your recommenders through the online system.

  • Request Process: You are highly encouraged to request recommendations before submitting your full application. Use the "Request Recommendations" tab in your SULI account to list recommenders; requests are sent automatically once listed.
  • Responsibility: It is your responsibility to ensure your recommenders submit their letters by the application deadline. Discuss your request with them in advance and allow ample time.
  • Quantity: A minimum of two recommendations is required; you may solicit up to three. Keep in mind, only the first two completed in the system will be included with your application.
  • Recommender Qualifications: Letters should come from individuals familiar with your education, training, experience, aptitude, or potential relevant to the SULI program. Suitable recommenders include STEM course instructors, internship mentors/supervisors, and research advisors.
  • Restrictions: Recommendations must come from professional or academic contacts who are aware of the applicant's STEM experience and aptitudes relevant to collaboration and the program. Letters of recommendation from family members, friends, social acquaintances (including friends of family members, peers, or classmates), religious leaders, or current/former SULI/CCI interns with whom the applicant shares a peer relationship, are not permitted. However, former SULI/CCI interns who are permanently employed at DOE labs or headquarters or served as an academic instructor/advisor are eligible to serve as a recommender.
