Graduate Admissions Checklist and Requirements

Students with a strong background in chemical engineering or related field are encouraged to apply. A bachelor of science degree in chemical engineering, or closely related field (another engineering field, chemistry, etc).

An undergraduate GPA of at least 3.0 on a 4.0 scale. Our most competitive applicants have a GPA of 3.5 on a 4.0 scale, or 88% out of 100% or 1st Class with Distinction. If applicable, a graduate GPA of at least 3.0 on a 4.0 scale.

1. Application

2. Supporting Documents (to be uploaded with your online application)

  • Statement of Purpose: 

A one to two page statement of purpose outlining your motivation for attending our program and your goals after receiving the degree. This essay allows you to express your interest in chemical and biomolecular engineering, describe what area(s) interest you the most, and goals that you have for applying the training received here. Since most of the material supplied with the application is little more than numbers, data, and grades, this statement allows you to "speak" to the faculty reviewing your file and gives them a glimpse into your motivations. Please be sure to include your full name on this document.

  • Resume or CV:

Serves as a helpful means of summarizing the background of an applicants. Please keep the length of this document to under two pages. If possible, please include class rank in your CV.

  • Transcripts:

Transcripts can be submitted electronically or as a hard copy. The can be submitted via the following means:

  • Uploaded via the prompt in the online application
  • Submitted electronically to gpadocs@osu.edu.
  • Submitted via postal mail. The mailing address is located at the side of this page.

Official scanned copies of transcripts from all post-secondary institutions are required. We will not review an application for admission consideration without scans or physical copies of official transcripts on record. Anything other than scans of official transcripts will result in a delay in processing your application.

If you are an international applicant, you must upload scans of official transcripts with degree statements (proof of degree) in their original language, along with English language translations that follow the format of the original documents.

Any questions surrounding transcripts, including what is acceptable or not, should be directed to  . The Office of Graduate and Professional Admissions oversees all transcript related questions.

Ohio State students: Ohio State students are only required to submit transcripts from other institutions attended, if any. Ohio State transcripts will be obtained internally for the review process and do not need to be submitted with your application.

Important: If admitted, a final official copy of all transcripts will be required at that time by the Graduate Admissions Office. A hard copy is not required as a part of the application process.

3. Three Letters of Recommendation

  • Online submission: During the application process, applicants will be prompted to enter the e-mail addresses of their recommenders. The Graduate Admissions Office will automatically send an e-mail to these addresses with details on how to submit an online reference letter once you submit your online application. Applicants are encouraged to contact their references to be sure they received the instructions from the Graduate Admissions Office and have provided a recommendation.

For students that apply, we would appreciate if your letter of recommendation writer could provide information about:

 “the intellectual ability of the nominee, the quality and quantity of scholarly work and other attributes of the nominee such as experiences, leadership activities, motivation, work-ethic, overcoming hardship(s), and promise for success in graduate school.”

4. Submit offical TOEFL Scores (if applicable):

  • TOEFL scores are required of all applicants whos native language is not English. No student will be considered for admission until proof of English is received. If a student receives a degree from a U.S. institution, TOEFL scores are not needed. (Our most competitive applicants have scores of at lest 100 (TOEFL iBT). WE PREFER THE TOEFL TEST.

Note: Applicants must submit official scores via Educational Testing Services (ETS) to the OSU Admissions Office (institution code 1592, no department code is necessary).

GRE Scores are no longer required. But you can include them if you would like.


We do occasionally admit students who have undergraduate degrees in subjects other than chemical engineering. However, these students will need to take make-up course work to succeed in our graduate program. These students must take the following undergraduate courses or have equivalent coursework in the following subject areas:Prerequisites for non chemical engineering majors:

  • Thermodynamics: CBE 3508
  • Transport Phenomena (Momentum and Mass Transfers): CBE 2420 and 3521
  • Chemical Engineering Kinetics: CBE 3610
  • Engineering Mathematics (Ordinary and Partial Differential Equations): Math 2177 or equivalent

Visitation Weekend: 

For those students who are in the U.S. and are admitted to our PhD program, there will be a department visitaiton. Details will be released at a later time. If you cannot attend during this time an individual visit can be arranged. More information will be sent out in January.
