Application Forms

CU Boulder has an online application system.  Please contact us if you have any questions or problems with the online application.

Graduate Records Examination (GRE Test)

The general GRE is required for all applicants. GRE scores for the general test should be in the upper 33% range, and in the upper 50% range for the subject test. We strongly encourage, but do not require applicants to take the GRE subject test in Chemistry or Biochemistry.

Our institution code is #4841. The department code for GRE scores is no longer required by CU Boulder, however is you need to input a code when you take the test please use one of the following department codes for Chemistry and Biochemistry: #0202, 0301, 0302, 0304, 0306, 0399.

You may self-report your GRE scores in your initial application, but the official scores must be sent directly to CU from ETS for the application to be considered complete. Photocopies and personal notices of GRE scores are not considered official.

GPA Requirements

The minimum undergraduate GPA for graduate studies in Chemistry and Biochemistry is 3.0.


In general all graduate students receive support as teaching assistants in their first year, and as either teaching or research assistants for the duration of their studies. In addition, tuition is paid by the Department at the out-of -state rate for the 1st year (for non-Colorado residents) and thereafter at the in-state rate (for US citizens and permanent residents). International student tuition is fully covered at the adjusted rate set by the Graduate School, as part of the teaching or research assistantships.

International Students

We expect all of our students to have excellent oral communication skills. If your native language is not English, then we require you take the TOEFL or an acceptable equivalent examination.

The minimum scores for English Language Tests are:

Test Type Score
Internet-based TOEFL 100

The TOEFL department code for the internet-based, computer-based and paper based test is 62. If your TOEFL score is close, but does not meet the departmental minimum a phone interview may be required to determine English communication skills before an offer of admission is made.

Official TOEFL scores must be sent from ETS. Photocopies, are not considered to be official, and cannot be accepted in lieu of the official notification from ETS. You may self-report your scores on the initial application, but please have the scores sent from ETS as soon as possible.

Note: No TOEFL is required if you have completed at least one year of full time study at a  U.S. Institution ( or at an institution in a country where English is the native language) at the time you apply and within two years from your desired admission term. 

Transfer Students

Students may qualify to transfer up to ten credit hours for their PhD graduate studies. These credit hours cannot have been used toward their undergraduate degree. The transfer credits will be evaluated after the student has been with the department for one semester, and the student must be in good standing.

MS Students

With the exception of active US military students, the Department rarely accepts students for an MS degree.
