Application Materials

You will be required to upload a copy of your transcript into your admissions portal, but an official transcript will be requested if you are admitted to the program. When it is received, you will be enrolled.

A $75 fee is typically required alongside your application, but we offer waivers. If you are a first-generation college student, have participated in a program such as NNE or SACNAS (among many others), or are unable to apply because of the fee, please contact us at

For PhD applicants three, and for MSE applicants two. We require that your recommenders submit their recommendations online. The application allows you to submit three letters online.

If you have worked for several years, it is expected that some of the letters will come from non-academic sources. What should be avoided is having mostly non-academic letter writers when your last several years have been in academia, and vice-versa.

We require the use of the online application recommendation section for recommenders’ submissions. Choosing this option in the application will trigger an email to your recommender with explicit instructions on how to submit.

The official form is a part of the online recommendation. Comments will be accepted even if the official form is not used. However, we strongly encourage the form to be used because it includes a table which provides us with additional information.


Our institution code is (4655) for the GRE and (C559) for the TOEFL exam. Our department code for TOEFL is (78) and for GRE is (0402).

This and other information concerning Standardized Testing can be found at the ETS GRE Website.

The aptitude GRE is required for MSE and PhD applicants. Preferred scores are Verbal: 153 (62%) or above, Quantitative: 160 (84%) or above, TOEFL: 100 or above and IELTS: 7 or above.PhD applicants may obtain a waiver to exempt them from submitting GRE scores. Waivers may be obtained by contacting and providing: a.) your Slate application reference number; b.) the reason for why you’re unable to provide GRE scores.

All non-native English speakers MUST take the TOEFL exam or IELTS. Neither the TWE nor the TSE is required, but is recommended.

The Department of Computer Science does accept IELTS.

Copies will be accepted although it is best to have your GRE scores sent through ETS. Applicants should request recent GRE scores from ETS and submit them to Johns Hopkins before the application deadline. In order for your application to be reviewed, you must include the university’s institution code in your request to ETS. Johns Hopkins University School of Engineering’s institution code is 4655.

TOEFL results should be sent directly to the Engineering Graduate Admissions Office by either the IELTS Global Recognition System or the Educational Testing Service (ETS) which administers TOEFL. International English Language Testing System (IELTS).

If admitted, you will be required to submit your official final documents directly to the G.W.C Whiting School of Engineering Graduate Admissions office.

The scores must be new enough that ETS still considers them valid and will provide an official score report. Currently, the ETS sets this limit at five years.

The masters program highly regards a minimum verbal score of 153, quantitative score of 160 and TOEFL of 100.

Getting Accepted

First we consider the source of the letter. A letter from your cousin who happens to teach at a two-year college is weighed significantly less than a letter from a researcher at a top computer science school! Next, we look for evidence of research potential. In particular, evidence of outstanding performance in past projects is of high importance. Somewhat less important is evidence of outstanding ability in the classroom. A good letter writer should know you well and be able to rank you very favorably in comparison with your peers.

Yes, we do. Both your grades and courses are important, primarily your grades in CS courses during the last two years of undergraduate study.

Previous research experience is the easiest way to be placed on the top of the applicant interest list. For this reason we encourage you to send a link to detailed information on your past research experience if you have any. Projects performed for classes, as part of a job, or on your own are also important, in particular if the projects are research-related. Make sure to include a description of these projects with your application – better yet is a link to an online file. Previous teaching experience also improves your chances.

Statements of purpose are very important, as they allow us to better form a picture of each applicant, and convince us that you have the attitude needed to succeed in a graduate program.

The Graduate Affairs and Admissions Office does not accept paper copies of the statement of purpose since applicants are expected to submit this document through the online application. The uploaded file cannot exceed 500KB in size. The document must also adhere to 1″ (inch) margins. With regards to a Sample of Work (if your department requires this or its applicants have a habit of submitting it anyway), the online application can only accept samples of work up to 500KB in size. The document must also adhere to 1″ (inch) margins. We only accept samples of work via paper that exceed the 500KB size limit. Please do not send duplicates of documents that were successfully uploaded to the online system.

We encourage you to include any information that you think will help us make a more accurate assessment of your abilities. However, it is generally better to give short abstracts of papers or projects (links to online versions are better) rather than full papers or reports. We cannot read everything that everyone sends since every year we receive over 300 PhD applications and 300 MSE applications.

Many first-year PhD students in the department are given teaching assistantships (TA). A few students are given fellowships, and a few start directly as research assistants (RA). By their third year, nearly all students are supported by an RA-ship from an individual professor.

The department regrets that we are unable to give financial aid to MSE students. Once you are here, however, you can apply for part-time student work as a course assistant or for other types of work, but we cannot grant tuition waivers for this work. MSE students are never given a stipend of any form, but may be hired on an hourly basis.

A $75 fee is typically required alongside your application.

If you satisfy all the qualifying requirements for the PhD and a professor wishes to serve as your PhD thesis advisor and secure financial support for your research, you can become a PhD candidate. You will still have to apply for admission into the program and be approved by the Admissions Committee and the Chair of the Department.

Entering students are expected to have completed a program of study equivalent to that required by the B.S. in computer science. Applicants from other disciplines are required to have coursework (or equivalent experience) in intermediate programming (C++ and Java), data structures, automata theory, computer systems fundamentals and algorithms.

Full-time working professionals should apply to JHU’s Engineering Programs for Professionals. This is a completely separate program from the day school, and offers a large number of computer science courses online, in the evening and during the summer at several locations in the Baltimore-Washington area, leading to the MS degree or Post-Master’s Certificate. No PhD degrees are offered online.
