The Department of Logic and Philosophy of Science and the Department of Philosophy jointly administer a Ph.D. program in philosophy with two independent tracks:  the Philosophy Track and the LPS Track.

The remarks on this page are only for applicants to the LPS Track.
Those interested in the Philosophy Track must apply to the Philosophy Department.

Applicants for the LPS Track must have a bachelor's degree, but there is no formal requirement as to the field of that degree. The most natural undergraduate majors for LPS graduate students would be philosophy, mathematics, or the sciences, but those with other degrees who are interested in the fields of LPS should feel free to apply.

Deadline and How to Apply

All applicants must apply online using the UCI Online Application for Graduate Admissions. (The degree code for the LPS Track of the Philosophy Ph.D. is 1448.)  Paper applications are no longer used.

Applications will be accepted beginning September 1st. The deadline for submission is December 15th.

Application Requirements

The following items are required as part of the graduate application:

  • Application Fee - US $120 (US Citizens and Permanent Residents); US $140 (international applicants). See below for information about fee waivers.
  • GRE score ***Update: GRE scores are optional for the 2021-2022 admissions cycle due to COVID-19.***
  • Transcripts
  • TOEFL or IELTS (for non-native speakers of English; see below)
  • Three (3) Letters of Recommendation
  • A writing sample
  • A statement of purpose

In addition, an interview is required prior to admission.

You'll be required to submit all supplemental application materials electronically, direct through the on-line application you will create in the campus application system, Slate.

We require only a single transcript from each school attended, uploaded by the applicant. We are no longer able to accept paper documents through the mail, or to upload electronic supplemental materials on the applicant's behalf.

Unofficial transcripts are acceptable for admission consideration. All admission offers will be provisional. Those who are offered and accept admission and financial support will then be required to submit official documents before the start of the Fall 2019 term, to clear the provisional admission status.

The writing sample need not deal with a topic in logic and /or philosophy of science -- though that is desirable -- but should exhibit the applicant's ability to argue clearly and carefully. The personal statement should explain the applicant's interests and provide any additional information that he or she would like the Department to consider. 

Most application fee waivers are available to qualifying US citizens and permanent residents: http://www.grad. to-uci/fee-waivers.php.  Please note a number of University-wide diversity related fee waivers are availale: https://grad.uci. edu/admissions/applying-to- uci/fee-waivers-list.php.  In addition, the LPS department will waive fees for participants in the LPS Summer Diversity Program, the Wonder Philosophy workshop, the MCMP Summer School in Mathematical Philosophy for Female Students, and the Pittsburgh Summer Program.

Graduate Record Exam (GRE)

***Update: GRE scores are optional for the 2021-2022 admissions cycle due to COVID-19.***

The GRE General Test is required of all applicants for PhD admission. We cannot waive this requirement, even when the applicant has completed an advanced degree at another college or university in the United States.

The ETS institution code for the University of California, Irvine is 4859. The GRE departmental code for the Dept of Logic and Philosophy of Science is 2801.

We cannot accept GMAT, LSAT, or MCAT scores in place of the GREs. We do not require that applicants file scores from any of the various GRE (subject) tests available.

Test scores may be dated no earlier than February of five years before the Fall a student would matriculate, so, for instance, for Fall 2018 admissions, the GRE must be dated February 2013 or later.

Test of English as a Foreign Language (TOEFL) and International English Language Testing System (IELTS)

The internet-based TOEFL(-ibT) is required of all international applicants except citizens of Australia, Canada, New Zealand, South Africa, and the United Kingdom. The test is also required of US permanent residents who did not attend four full years (and graduate) from high school in the United States.

In some cases, it is possible to waive the TOEFL (or equivalent) requirement for applicants who have completed high school, undergraduate, or advanced degrees in English speaking countries, as described here. However, be aware that it is University policy that international students who are not citizens of countries where English is the primary or dominant language (as described here) must take the TOEFL or an equivalent test before accepting a TA appointment; waivers for this requirement cannot be made. Moreover, for many international students, the TOEFL is a valuable source of information for the admissions committee. For these reasons, we recommend submitting a TOEFL score even if it is possible to have the requirement waived.

The ETS institution code for the University of California, Irvine is 4859. The TOEFL departmental code for the Dept of Logic and Philosophy of Science is 80.

A minimum overall score of 80/120 is required for admission, while a minimum sub-score of 26/30 on the Speaking component of the test is needed to qualify for financial support consideration. We cannot waive either of these minimum score requirements under any circumstances. Neither can we waive the requirement for current TOEFL or IELTS scores.

We can accept current IELTS (International English Language Testing System) scores as an alternative to the TOEFL-ibT, in which case a minimum 7/10 (overall) is required for admission, and 8/10 (Speaking component) for financial support consideration.

TOEFL-ibt or IELTS test scores may be dated no earlier than February of two years before the Fall a student would matriculate, so, for instance, for Fall 2018 admission, the TOEFL or IELTS must be dated February 2016 or later.
