How to Apply

All applicants must submit

1. A completed online application.
2. Three Letters of Recommendation: References can be academic or professional in nature.
3. Curriculum Vitae or Resume
4. Unofficial Transcripts: Upload an unofficial copy of your transcript(s) from all undergraduate and graduate institution(s) you attended. This includes community colleges, summer sessions, and extension programs. Failure to list and submit transcripts from all institutions previously attended is considered to be a violation of academic ethics and may result in the cancellation of your admission or dismissal from the university.
   • Instructions for Uploading Unofficial Transcripts to Your Application 
   • If you receive an offer of admission and confirm your intent to enroll, you will be required to submit your official transcripts. Do not send official transcripts until a final official transcript is available - including all graded coursework and degree with graduation date. Official transcripts must match the unofficial ones submitted with your application.
5. Personal Statement: Limited to two pages and should address the following areas:
   • Why do you want to attend CU Boulder and what is your preparation for this field of study?
   • What are your scientific and professional goals, and other aspects of your background / interests which may aid the admission committee in evaluating your aptitude and motivation for graduate study
   • If you are interested in pursuing research as part of your degree, please include the following information in your personal statement:
     • What are your research interests?
     • Are there any faculty you are specifically interested in working with?
     • Please include if you have external funding, such as government fellowships, corporate sponsorships, etc.
   • Mortenson Center Graduate Certificate applicants should also include in their statement of purpose:
     • How your previous experience (EWB, Peace Corps, professional, etc.) prepares you for the Mortenson Center in Global Engineering program.
     • A description of language training you have received to prepare yourself for Mortenson Center in Global Engineering-related activities and your level of fluency in listening, speaking, reading, and writing in any language other than English.
     • State your clearly defined area of interest for graduate study in engineering for developing communities (i.e., water/sanitation/hygiene, energy, cook stoves, shelter, disaster relief, etc.)
     • An indication of how participating in this program will further your academic and professional ambitions.
6. GRE: The GRE is not required. 

International students must also submit

1. TOEFL, IELTS, or Duolingo score, if applicable.
   • The English proficiency requirement will be waived if you have completed at least one year of full-time study at a US institution (or at an institution in a country where English is the native language) at the time you apply, and are within two years from your desired admission term. Your transcripts are used to confirm this. Non-native English speakers should only provide certification of adequate spoken and written English.
   • Preferred scores for the English proficiency exams are:
     • TOEFL 90 (only internet-based tests are accepted)
     • IELTS 7.0
     • Duolingo 120

If you have any problems or questions during the application process, please contact the department’s graduate program advisor.
