Navigating Admissions to UCLA's Computer Science Graduate Programs: A Comprehensive Guide

The University of California, Los Angeles (UCLA) Department of Computer Science is a highly sought-after institution for aspiring graduate students. Offering both a Master of Science (MSCS) and a Doctor of Philosophy (PhD) program, UCLA provides distinct pathways for individuals seeking to advance their knowledge and careers in the dynamic field of computer science. This guide aims to demystify the requirements and admissions processes for these esteemed programs, drawing upon detailed information provided by the department to ensure prospective applicants are well-informed and prepared.

Understanding UCLA's Computer Science Graduate Offerings

UCLA's Department of Computer Science offers two primary graduate degrees: the Master of Science in Computer Science (MSCS) and the Doctor of Philosophy (PhD) in Computer Science. While both programs delve deep into the intricacies of computing, they cater to different career aspirations and academic goals.

The Master of Science in Computer Science (MSCS) Program

The MSCS program is a well-established, two-year course of study that has been a cornerstone of computer science education at UCLA for over five decades. This program is meticulously designed to cultivate the next generation of computing professionals, equipping them with the requisite depth and breadth of computer science knowledge. The MSCS program itself does not have declared fields of study, allowing students flexibility in their coursework. However, the field that MSCS applicants select in their online application will be instrumental in assigning admitted students to an initial faculty advisor. This program offers two distinct pathways for culminating a student's academic journey: a Capstone project or a thesis.

The MSCS Capstone project is a student-driven endeavor, where students are empowered to select their own topic and identify a faculty advisor from the Computer Science department to guide their work. This project is advised by faculty within the Department of Computer Science, providing practical, industry-relevant experience.

Alternatively, students in the MSCS program can opt for a thesis option instead of a Capstone project. The MS thesis option is specifically designed to offer in-depth research opportunities, allowing students to collaborate closely with CS faculty on cutting-edge research.

It is important to note that the MSCS program is a self-supporting professional degree, meaning that students are generally responsible for their own financial support. While Teaching Assistant (TA), Graduate Student Researcher (GSR), and Reader positions are valuable opportunities, they are not guaranteed for MSCS students and are not part of the program's curriculum. Prospective international MSCS applicants must be prepared to demonstrate sufficient financial support for their program of study, a requirement that will be requested if admission is offered.

The Master of Engineering (MEng) Program

Distinct from the MSCS program, UCLA's Samueli School of Engineering also offers a one-year Master of Engineering (MEng) degree. This program is a newer offering, designed to be self-supporting and professional in nature. The MEng degree is specifically tailored to address the needs of both students and industry, with a focus on preparing individuals for technical management positions. It aims to develop future engineering leaders by equipping them with a high-tech skill set combined with management acumen.

The Doctor of Philosophy (PhD) in Computer Science Program

The PhD program at UCLA is a more research-intensive and selective path, preparing students for careers in research and academia, or for advanced roles in industry that involve significant innovation and knowledge advancement. PhD candidates are expected to demonstrate substantial achievement and/or potential for advancing knowledge through independent research and teaching.

While a PhD degree prepares students for a wide array of careers, those who apply for a PhD typically demonstrate a strong inclination and aptitude for rigorous, independent research. The admissions committee generally does not consider PhD applicants for admission into the MS program, and vice versa, maintaining the distinct focus of each degree. However, a unique provision exists for PhD students: if a student has not previously earned an MS degree in computer science or a related field, they may petition to earn an MS degree concurrently with their PhD. In such cases, the PhD Written Qualifying Exam (WQE) can be substituted for the MS comprehensive exam or thesis requirement.

For PhD applicants, identifying potential faculty advisors is a crucial step. Applicants are asked to identify three CS faculty members with whom they are interested in working. These selections play a significant role in the department's efforts to identify potential faculty advisors for admitted students. Furthermore, all admitted PhD students are provided with financial support, typically through departmental resources or faculty research grants, and are given priority consideration for TA and GSR positions.

Admission Requirements: A Detailed Breakdown

Navigating the application process requires careful attention to specific academic prerequisites, standardized testing, and application materials. UCLA's Computer Science department has stringent yet clear requirements for both its MSCS and PhD programs.

Academic Prerequisites and Background

To be considered for admission to any graduate program in Computer Science at UCLA, applicants must hold a bachelor's degree from an accredited college or university. This degree should be comparable in standard and content to a bachelor's degree from the University of California. Crucially, applicants must possess the necessary academic preparation to successfully complete graduate-level courses in computer science.

While the vast majority of applicants have an undergraduate background in computer science, the department acknowledges that other majors such as electrical engineering, mathematics, statistics, and physics can provide a strong foundation. For undergraduate coursework, the department recommends:

Mathematics: Two years of calculus (including differential equations) and an introduction to discrete structures.
Physics: One year of physics, covering mechanics, oscillations, waves, and electric and magnetic fields.
Statistics: At least one statistics course.

Beyond foundational mathematics and science, specific coursework in Computer Science is highly recommended. This includes:

Operating Systems Principles
Computer Network Fundamentals
Computer Systems Architecture
Software Engineering
Programming Languages
Compiler Construction
Data Management Systems
Fundamentals of Artificial Intelligence
Introduction to Computer Graphics
Introduction to Algorithms and Complexity

It is vital for applicants to review the Computer Science course catalog and identify the prerequisites for graduate-level courses. Many graduate courses have prerequisites that are upper-division undergraduate classes, which are typically only offered at four-year institutions and not at community colleges. Failure to meet these prerequisites may result in an instructor not allowing a student to enroll in a course.

For applicants without a formal computer science background, eligibility is still possible, but requires a more robust demonstration of preparedness. Such applicants may be highly competitive if they possess significant professional experience in the field and have completed coursework equivalent to the upper-division undergraduate prerequisites, or have taken these courses themselves. UCLA does not offer transitional or pre-admission programs, nor does it consider applications for a second bachelor's degree.

GPA and Scholastic Achievement

The university mandates a minimum scholastic average of a B (3.0 on a 4.0 scale) or its equivalent for admission consideration. However, the department reviews all applicants who meet this minimum GPA. For a truly competitive application, particularly for the PhD program, applicants should aim for a higher undergraduate cumulative GPA, ideally at least a 3.5 on a 4.0 scale. For applicants who have already undertaken graduate studies, a GPA of at least 3.50 in any graduate coursework is also highly desirable. The Computer Science Graduate Student Affairs Office staff are responsible for reviewing and converting grades as necessary for all applicants.

Standardized Testing: GRE and English Proficiency

GRE (Graduate Record Examinations):For the Fall 2025-2026 Admissions cycle only, the GRE is not required. Applicants for this cycle are not mandated to take the GRE or submit a GRE score report. However, students have the option to voluntarily submit GRE test scores, which will be considered as part of a holistic application review.

For previous admissions cycles, a competitive GRE score was a requirement. There is no minimum GRE score requirement; rather, the department reviews scores as part of the overall application. If applicants choose to submit GRE scores, they must ensure they are sent to UCLA using the correct institution code: 4837 and the Computer Science department code: 0402. It is crucial to order scores to be sent by the application deadline. Scores are generally accepted if the exam was taken within five years of the submission date of the UCLA Graduate Division online application. The GRE Computer Science subject exam is not reviewed by the department.

English Proficiency (TOEFL/IELTS):International applicants whose first language is not English are required to demonstrate English proficiency by submitting scores from either the TOEFL (Test of English as a Foreign Language) or IELTS (International English Language Testing System).

TOEFL: A minimum score of 87 (computer-based) or 560 (paper-based) is required.
IELTS: A minimum score of 7.0 is required.

These exams must have been taken within two years of the date the online admission application is submitted. Similar to the GRE, applicants must ensure scores are sent to UCLA using the correct institution code: 4837 and the Computer Science department code: 78. Applicants are encouraged to submit unofficial score reports on the Supporting Documents Upload section of the online application while official scores are being processed.

Waiver for English Proficiency:The TOEFL/IELTS requirement can be waived for applicants who hold a bachelor's degree or higher from a university within the United States, or from a country where English is the primary spoken language of daily life AND the medium of instruction. This exemption also applies to individuals who have completed two years of full-time study at such accredited institutions.

Application Components and Deadlines

The application process for both the MSCS and PhD programs is managed through the UCLA application for graduate admission. Applicants must select "Computer Science MS" or "Computer Science PhD" as their intended program of study.

Application Deadline:The application deadline for all programs is strictly December 15th at 23:59 Pacific Time. In fairness to all applicants and to ensure the efficacy of the selection process, applications and supporting materials submitted after this deadline cannot be guaranteed for review.

Key Application Materials:

Online Application: The primary portal for submitting all application materials.
Transcripts: Applicants are required to upload ONE (1) official transcript from each post-secondary institution attended. Official transcripts are defined as original documents issued by the institution bearing the Registrar's signature and the institution's seal. International applicants should consult the Graduate Division's webpage for specific requirements regarding foreign academic records. If admitted, a final transcript indicating degree conferral may be submitted during the summer. UCLA students and alumni are exempt from submitting UCLA transcripts.
Letters of Recommendation:
- MSCS Program: At least THREE (3) letters of recommendation are required. For applicants with an Electrical Engineering and Computer Science (EECS) background, at least two letters should ideally be from CS faculty/instructors. If you are an ESAP applicant to the CS MS program, you will need two letters of recommendation from CS faculty/instructors or instructors from outside the department who hold a joint appointment with the UCLA CS Dept.
- PhD Program: A minimum of THREE (3) letters of recommendation are expected. For PhD applicants, it is strongly urged that all letters be from academic or professional references who can comment on recent accomplishments and qualifications for graduate study in Computer Science. If an applicant holds an MS degree, letters from professors who served on their MS thesis committee are highly valuable.All letters of recommendation are due by the December 15th deadline.
Statement of Purpose (SOP): All applicants must submit a Statement of Purpose (SOP) with a 500-word limit. The SOP is considered the primary writing sample for the application.
Personal Statement: A separate personal statement, also with a 500-word limit, is required.
Resume or Curriculum Vitae (CV): Applicants are not required to submit a resume or CV.
Fee Waiver: Information on fee waiver criteria can be found on the dedicated Fee Waiver requirement page. If an applicant meets the criteria, it is their responsibility to upload all required documentation (including redacted SSNs) within their application before submission. Modifications to the application or materials after submission are not permitted. Fee waiver materials submitted after the deadline cannot be guaranteed for review.

Important Considerations for Applicants

Application to MS or PhD Only: Applicants may apply to either the PhD program or the MS program, but not both. The admissions committee generally does not consider PhD applicants for the MS program, or vice versa.
Master's Degree Holders: Applicants who already hold or are currently enrolled in a master's degree in computer science or a closely related discipline (such as information sciences or data systems) will not be considered for admission to the MSCS program. They are, however, welcome to apply to the PhD program.
Current UCLA Graduate Students: Current UCLA graduate students in other departments are not permitted to transfer into the MSCS program. Admission to the MSCS program is only granted to formally admitted MSCS students who applied during the admissions cycle.
Incomplete Files: While the office strives to match test reports and transcripts for nearly all applicants, it is the applicant's responsibility to ensure all required materials are submitted by the deadline. An applicant may be denied admission consideration due to an incomplete file only if they do not respond to requests to submit missing materials.
Application Modifications: No modifications or edits to the admissions application or submitted materials (e.g., Statement of Purpose, Personal History) are allowed after submission.
Admission Deferrals: The department does not offer admission deferrals.
Re-applicants: Re-applicants are welcome and are encouraged to strengthen their candidacy. A new online application must be submitted for each application cycle.
Distance Learning: Neither the MSCS nor the PhD program incorporates distance learning courses. Students must be registered and enrolled for a minimum of 12 units each quarter.

Program Duration and Academic Progression

The duration of study for graduate programs at UCLA can vary.

MSCS Program: On average, the MS degree is completed in five quarters (approximately 20 months, or two academic years). However, some students may require six quarters (2 full years) to finish their degree requirements.
PhD Program: The normative length of time for the PhD program is typically longer, with students expected to complete their degree within a specified timeframe, often around five to seven years.

Students are expected to register every term unless granted a formal leave of absence, including the term in which their degree is to be awarded.

Research Interests and Faculty Alignment

A critical aspect of the graduate admissions process, particularly for the PhD program, involves aligning applicant research interests with faculty expertise. Applicants to both the MSCS and PhD programs are encouraged to identify specific CS faculty members whose research aligns with their own interests. This is a key component in the department's process of identifying potential faculty advisors. Prospective students are strongly advised to thoroughly research the faculty profiles and ongoing research projects within the UCLA Computer Science department to identify potential mentors.
