PRODUCING A BETTER APPLICATION:
The Columbia University Department of Computer Science is looking for students who have excellent research potential in computer science as well as good grades, test scores, and English language skills. Evidence that you possess these will help your case. So be sure to include with your application materials any evidence of your research experience and qualifications, including substantial course projects or technical employment. Publications in international conferences and journals are important to mention; you may want to submit up to two of your best such papers in the “Research Papers” section of your online application. You must also submit your curriculum vitae/resume, which should list all papers that you have co-authored. If possible, at least two of your recommendation letters should address your research qualifications.
You should also carefully choose the “Areas of research interest” and the “Professors and researchers with research interests close to yours” in the “Research Interests” section of your online application. This section is critical to match faculty and Ph.D. applicants, and hence to make admission and funding offers to applicants. Carefully review the background, interests, and current directions of faculty members before contacting them by email. If you live in the area or will be visiting New York City, request an in-person interview with faculty members whose research interests are close to yours. Arrange any visit far in advance; do not just arrive unannounced, or you will almost certainly be disappointed when no one is available to see you. (Note: do not request a meeting with the Ph.D. Admissions Chair unless he/she happens to be one of the faculty you are considering for an advisor. The Ph.D. Admissions Chair does not interview applicants.)
It is usually best to ask professors from your current or most recent academic institution. Research supervisors are strongly preferred over classroom teachers, unless the course(s) involved a substantial project. Otherwise, it is better to obtain letters from faculty who gave you high grades. Obtain letters from regular faculty members if at all possible, rather than from adjuncts, staff, or graduate students. Supervisors from summer internships, particularly research labs, are also good choices.
Applicants returning to school after several years away from academia should submit recommendations from work supervisors and advanced colleagues, preferably those who hold a graduate degree and/or have published articles in major research forums. It is less useful in these circumstances to request letters from former professors who have had no contact with you in many years. It is not recommended that you submit character references from people with no academic or research experience or from persons who are unfamiliar with your academic credentials, your technical, research, or teaching experience, or with your qualifications and research potential. Do not write your own letters. It is generally useful for your references to include in their letters information about their own background (e.g., whether they hold a Ph.D. degree themselves and from what school, whether they have held a faculty position in the past at a major university, and so on).
You can certainly submit a three-page document, but a concise one-page statement is preferable. The department must consider many hundreds of applications, so a short statement focused on your research experience, interests, and goals, is generally most effective. Except in unusual circumstances, information on your personal history, childhood, and how you became interested in computer science is less useful.
Yes, you can. However, we cannot guarantee that these will be considered during the review of your application, since we try to review applications as soon as they are officially complete.
You may certainly apply to the Ph.D. program without a Master’s degree. Many of our Ph.D. students come to our department directly after receiving their Bachelor’s degree.
The Spring 2021 deadline for new Ph.D. Applications is November 15.
To start the Ph.D. program in the fall, the application deadline is December 15 of the previous year. For more information, please check out the Ph.D. section of our admissions page.
Yes, you can still apply. However, be aware that applications are usually reviewed soon after the deadline, so late applications may not be processed as quickly or have the best chance of getting funding from our department.
STANDARDIZED TEST SCORES:
The Graduate Record Examination (GRE) is not required for 2021 admission cycle. This includes Spring 2021 and Fall 2021. If you have taken the exam and would like to provide your scores, you may, but it is not required. Students who do not submit scores will not be penalized in the graduate admissions review process.
Test of English as a Foreign Language (TOEFL), International English Language Testing System (IELTS), Pearson Test of English (PTE Academic), or Duolingo English Test (DET). For the 2021 application year, we will accept the IELTS Indicator, TOEFL iBT Special Home Edition, and TOEFL ITP Plus for China Solution. The ETS School Code for the Fu Foundation School of Engineering and Applied Science is 2111.
Please have your official GRE and TOEFL scores sent to us directly by ETS, using the Columbia University institutional code 2111. It is not necessary to enter the department code.
For IELTS scores, enter your TRF number on the application for admission. Our office downloads IELTS scores that have been transmitted to our e-download account. Please contact your test center and request that your scores be sent to the IELTS e-download account. You may select Columbia Engineering, by searching for Columbia University under “List of Organizations subscribing to the E-TRF Query” and then selecting “The Fu Foundation School.” We will not accept paper IELTS test report forms.
Yes, you can still apply. Please follow all of the following steps:
- In the “Test Scores” section of the online application system, check the appropriate “score not yet known” boxes.
- Once you are informed of your test scores, report the scores in the “Test Scores” section of the online application system, even if you learn your scores after the application deadline. We use your self-reported scores in the application review process while we wait for the official score reports from ETS, so it is important that you self-report your results as soon as you learn about them.
- Ask ETS to submit official score reports to us using institution code 2111, following the instructions in the “Test Scores” section of the online application system.
Unfortunately, no. Your test scores must be valid as of the application deadline. Scores that expire before the deadline will not be accepted.
There are no minimum test score requirements. As a reference, however, the average GRE scores for the entering class of Fall 2014 were Verbal: 159, Quantitative: 166, and Analytical: 4.3. The average TOEFL iBT score was 106. If instead of the TOEFL you take the IELTS exam, your IELTS scores should be at least 7.
Yes. You must both self-report your test scores in your online application, and request that an official score report be sent directly by ETS (for the GRE and TOEFL exams) and by IELTS, if appropriate, to Columbia University. The unofficial scores will be verified against your official scores. All GRE scores are valid for five years. TOEFL and IELTS scores are valid for two years.
Only two groups of applicants may be exempted from this requirement: (1) applicants who have applied to any Columbia FFSEAS Computer Science graduate program in the last year and (2) current Columbia FFSEAS graduate students. If you are in groups (1) or (2) and have submitted official scores to Columbia in the past, there is no need to send your official score report again as long as your test scores are still valid as of the application deadline. Note that you still must enter those scores yourself in your online application. If your test scores expire before the application deadline, then you must retake the exams. We cannot make exceptions to this rule.
No, in this case you do not need to submit your TOEFL/IELTS scores, as long as you will have completed your Master’s degree before starting your Ph.D. at Columbia.
Yes, you do. The TOEFL or IELTS exam is required for all applicants who have received their undergraduate degree in a country where English is not the official and spoken language, unless they will have completed a Master’s degree in the U.S. before starting their Ph.D. at Columbia. Working in the U.S. does not exempt you from taking the TOEFL or IELTS exams.
Note that you must report your unofficial test score in the online application, and also request that an official score report be sent directly to Columbia University, as specified in the “Test Scores” section of the online application. The unofficial scores will be verified against your official scores. TOEFL and IELTS scores are valid for two years. We cannot accept old scores so please do not request an exception.
Only two groups of applicants may be exempted from this requirement: (1) applicants who have applied to any Columbia FFSEAS Computer Science graduate program in the last year and (2) current Columbia FFSEAS graduate students. If you are in groups (1) or (2) and have submitted official scores to Columbia in the past, there is no need to send your official score report again as long as your test score is still valid as of the application deadline. Note that you still must enter the score yourself in your online application. If your test score expires before the application deadline, then you must retake the exam. We cannot make exceptions to this rule.
No, we do not require these exams. You do not need to take the TSE and TWE tests.
GRADES AND TRANSCRIPTS:
Materials that are not in English must be translated by an official and notarized transcription agency. You must find such agencies yourself; we cannot provide referrals, unfortunately.
Several agencies provide grade-translation services. You must find such services yourself; we cannot provide referrals, unfortunately. As a reference, here is the key for our grading system:
Letter Grades and Numerical Equivalents:
A+/A A- B+ B B- C+ C C- D+ D D- F 4.00 3.67 3.33 3.00 2.67 2.33 2.00 1.67 1.33 1.00 0.67 0.00
APPLICATION STATUS AND DECISIONS ON ADMISSION:
All official GRE exam and TOEFL/IELTS scores for all graduate programs in the School of Engineering are sent to the Office of Graduate Student Affairs. You may contact this office at firstname.lastname@example.org to confirm receipt of your scores. The staff will respond to your requests whenever possible. Please be aware that during peak periods, when the volume of inquiries is high, the Office of Graduate Student Affairs might not be able to answer your requests. However, if additional materials are needed for your application, you will be contacted by email.
Unfortunately Ph.D. admissions staff cannot answer these questions. As soon as a decision is made, you will be notified by email to the address that you specified in your online application.
Unfortunately, the volume of applications that we receive every year makes it impossible for us a) to admit all of the highly qualified persons who apply to our Ph.D. program or b) to provide specific feedback on our decisions. We understand that the application process is extremely stressful, and we deeply regret that we cannot provide specific reasons why individual applicants were not accepted into the program.
M.S. VS. PH.D. PROGRAMS:
They are completely independent programs with separate admissions; one does not “lead to” the other. Some students complete the “terminal” M.S. program first and then apply to the Ph.D. program; some students enter the Ph.D. program directly without an M.S. degree; other students complete their M.S. degree at some other institution prior to enrolling in our Ph.D. program. Some students leave after completing the M.S program.
Not necessarily. After completing your M.S. degree you would still have to apply (again) to the Ph.D. program. You cannot automatically transfer from the M.S. program to the Ph.D. program
This means you have *not* been admitted to the Ph.D. program but that you *have* been admitted to the M.S. program. Recall that the application form asked you if you would consider admission to the M.S. program if you were denied admission to the Ph.D. program. If you enter the M.S. program you may still apply again to the Ph.D. program next year.
Yes. After entering the M.S. program, you can re-apply to the Ph.D. program, and transfer to it if you are admitted.
There are three broad categories for financial aid:
- Federal Aid. Domestic students (i.e., U.S. citizens or permanent residents) are eligible to apply for scholarships, merit fellowships, and loans. International students cannot apply for this type of financial aid. Please refer to this page for further information and all inquiries.
- Institutional Aid/Departmental Funding. All applicants (i.e., both international and domestic students) who indicate in the online application that they would like to apply for financial aid will automatically be considered for funding by FFSEAS and by the Department of Computer Science. The Columbia Fu Foundation School of Engineering and Applied Science awards a small number of prestigious “Presidential Distinguished Fellowships” to new applicants. Eligible Ph.D. applicants for the fall semester will automatically be considered for these fellowships, which provide full financial support to their recipients. The department offers Graduate Research Assistantships (GRA). All applicants who indicate in the online application that they would like to apply for financial aid will automatically be considered for all these types of funding. It is not necessary to do anything else in order to apply for this funding.
- IGERT Fellowship. Qualified students who are either U.S. citizens or Permanent Residents should also consider applying to the IGERT program funded by the National Science Foundation. Please follow this link for details.
Generally many more students are admitted (with funding) in the fall than in the spring.
Probably, but not necessarily. You should specify the terms and time duration of your outside funding on your online application. Warning: if you are admitted “without support,” that really means you will not receive any financial support. It is not possible to apply for TA or GRA funding after admission decisions have been made. And please do not plan to “pay your own way” through outside employment: the Computer Science Department normally does not permit “part-time” Ph.D. students. (However, part-time students are common in the “terminal” M.S. program.)
Yes, as soon as a decision is made in this respect, you will be notified by email.
THE ONLINE APPLICATION SYSTEM:
Please log into the application system. You will be able to see the contents of each of your application’s sections, and check whether the data matches what you intended. You can change your application even after having “submitted” it.
Most of your application materials must be submitted online. The only exceptions are your official TOEFL/IELTS and GRE test scores. The official test scores should be sent to us directly by ETS (for the GRE and TOEFL exams) and by IELTS, if appropriate, using the correct school code and as specified in the “Test Scores” section of the online application system. All other materials, including letters of recommendation and transcripts, must be submitted electronically. Unfortunately, we cannot make exceptions to this rule.
Please try filling out the application using your current browser. If you run into any problems, we strongly suggest that you upgrade your browser and install its latest version. We cannot support older browsers, unfortunately.
Passwords are case-sensitive, so check your “caps lock” key. If you are still unable to login, then have the application system send you a new password to the email address that you provided. You can do this by just filling out your email address, with no password, in the main login page of the application system.
LETTERS OF RECOMMENDATION:
All recommendations should be submitted electronically by your recommendation providers. The application review process is handled completely electronically, so we cannot make exceptions to this rule.
The deadline for the arrival of the recommendations is the same as the deadline for the submission of the application. However, it is acceptable for your recommendations to arrive just a few days (e.g., a week or two) after this deadline. Be aware, though, that your application will not receive full consideration until all recommendations have been received.
There are no such forms. Instead, you need to add the name, email address, and any other required information for your recommendation providers in the “Recommendations” section of the online application system. After you have completed and submitted your application, we will contact by email each of your recommendation providers and give them instructions on how they can submit their recommendations. The recommendation providers submit their recommendations themselves.
Roughly speaking, we receive around 550 applications for fall admissions each year, and around 40 applications for spring admissions. We generally admit many more applicants to start in the fall semester than for the spring semester. Over the last few years, on average, we have had around 25 new Ph.D. students entering each fall and around 5 new Ph.D. students entering each spring.
All Ph.D. students are expected to participate in departmental and laboratory activity full-time on-campus throughout the program, except possibly for summer jobs elsewhere. Therefore, the department does not normally consider admission of part-time students.
No. Graduate students enrolled at other institutions or programs must apply through the regular Ph.D. application process.
Our school does not let students defer admission, unfortunately. So you will have to apply again. Note that if you were admitted before and you reapply within a year of your original application, then you do not have to pay the application fee, plus you might not need to send official test scores and transcripts. Please see the online application for more details.
Yes, you will have to apply and pay the application fee. However, you might not need to resend official test scores. Please go to the online application for more details.
All applicants must fill out the complete online application in all cases. However, if you are a current Columbia FFSEAS graduate student, then you do not have to pay the application fee, plus you might not need to send official test scores. Please see the online application for more details.
