Students with a Bachelor of Science degree in any engineering discipline, physics, or mathematics may apply to this program. Admitted students may be required to take additional courses to improve specific academic deficiencies before starting this program. For example, students must have had equivalent coursework in the areas of physics, chemistry, and differential equations.

I. Applicants should have earned a Bachelor's of Science degree (B. S.) or equivalent (eg., A.B.) and the following:

  • An undergraduate GPA of at least 2.75 out of 4.00
  • Scores at or above the 75th percentile on the GRE (Graduate Record Examination)

II. Minimum course requirements include:

  • 2 years of calculus, through differential equations
  • One year of physics

III. GRE (Graduate Record Examination) is required for all applicants. Lehigh graduates with a GPA of 3.0 or more are not required to take the GRE examination. We do not require the GRE subject test.

IV. The TOEFL (Test of English as a Foreign Language) is required for all applicants whose native language is not English.

  • If the applicant has received a degree in the United States, this test is waived. The minimum required score is 550 on the paper test and 213 on the computer version. The essay rating should be between 4.0 and 6.0. The TOEFL is only valid for two years from the date the test was taken.
  • Individual skill section score recommendations for Lehigh University and the iBT (Internet based TOEFL) are:
    • Writing - 20;
    • Speaking - 20
    • Reading - 20
    • Listening - 15
    • (Composite score = 79)
  • Any student with one or more individual skill section scores below these targets will be required to take an English as a Second Language (ESL) course or lab work during the initial academic year, concurrent with their regular department coursework. Any student with two or more skill section scores lower than these targets, and a composite score lower than 79, will be required to attend the StepUp Intensive English Program at Lehigh. The Lehigh ESL Department must be consulted regarding this requirement.

V. An official transcript from each university attended is required. All transcripts should be converted to the American 4.0 grading scale, if possible.

VI. Two (2) letters of recommendation are required from qualified individuals to evaluate the applicant's academic achievement and potential for graduate studies.


Applicants must apply directly to the Energy Systems Engineering Program. To be considered for admission, applicants must submit the following before the application can be reviewed:

  1. Online application available at
  2. Application fee of $75, payable to Lehigh University, which is non-refundable and cannot be waived.
  3. At least two letters of recommendation from qualified individuals, to evaluate the applicants academic achievements and potential for graduate studies should be submitted online. Official transcripts from all colleges and universities attended (in sealed envelopes direct from the Registrar at your previous institutions).
  4. Request copies of GRE score, with the official scores being sent to Lehigh University (Institution Code # 2365).
  5. Request copies of TOEFL score (mandatory for all international students), with the official scores sent by ETS (Educational Testing Service) to Lehigh University.
  6. Financial Aid form filled out with the supporting financial documents adding up to the total estimated yearly cost as printed on the form.
  7. A personal essay, on a separate sheet, summarizing of the applicants career objectives and work experience with reference to the chosen field of graduate study.


For prospective students applying for financial aid, the deadline for applications to the program is January 15. All other applications are due by May 15.
