The Johns Hopkins Engineering for Professionals Computer Science program offers students the most cutting-edge knowledge delivered in state-of-the-art facilities or online. Computer professionals, scientists, and engineers benefit from a full range of instruction and skills building in a variety of areas including theory, analysis, design, and implementation of information systems.

Upon completing the degree program, students will:

  1. Demonstrate mastery of the mathematical tools and methods used in analyzing the performance and efficiency of computer algorithms.
  2. Have the ability to determine the correctness of deterministic and non-deterministic algorithms.
  3. Demonstrate mastery of several important data structures useful in scientific programming and sorting/searching (Red-Black trees, B-Trees, Fibonacci Heaps, Disjoint Sets) and their associated creation and maintenance algorithms.
  4. Demonstrate mastery of several important graphs, algorithms, and their associated creation, maintenance, and application strategies.
  5. Demonstrate mastery of several important data structures useful in string search and their associated creation, maintenance, and application algorithms.


Master's Degree

Admission Requirements

  • You must meet the general admission requirements that pertain to all master's degree candidates.
  • Your prior education must include (1) one year of calculus; (2) a mathematics course beyond calculus (e.g., discrete mathematics, linear algebra, or differential equations); (3) a course in data structures; (4) a course in computer organization; and (5) a course in programming using a modern programming language such as Java or C++. (Prerequisite courses are offered to satisfy computer science and mathematics beyond calculus requirements.)
  • When reviewing an application, the candidate's academic and professional background will be considered.
  • If you are an international student, you may have additional admission requirements.
  • Bioinformatics Joint Program:
    • This program is offered jointly by the Zanvyl Krieger School of Arts and Sciences and the Whiting School of Engineering. Applications for admission to the Master of Science in Bioinformatics joint program must be submitted directly to Zanvyl Krieger School of Arts and Sciences.

Degree Requirements

  • Ten courses must be completed within five years.
  • Students are required to choose a concentration or track to follow.
  • The curriculum consists of three foundation courses and five courses from the Computer Science ( program, or from a list of selected courses from the Cybersecurity ( and Information Systems Engineering ( programs. At least three courses must be from the same track, and at least two must be at the 700-level or higher. Up to two electives may be selected from the Applied and Computational Mathematics (, Applied Physics (, and Electrical and Computer Engineering ( programs.
  • Electives from other programs require approval of the Computer Science program chair or vice chair. Transfer courses will be considered electives.
  • Only one grade of C may count toward the master's degree.
  • All course selections are subject to advisor approval.
  • Telecommunications and Networking Concentration:
    • Ten courses must be completed within five years.
    • The curriculum consists of three foundation courses from the program and seven concentration elective courses, a maximum of three of those may come from the Electrical and Computer Engineering ( program.
    • Students are strongly encouraged to take courses from both Computer Science and Electrical and Computer Engineering.
    • Students lacking an electrical engineering background or equivalent must take 525.202 Signals and Systems as an undergraduate prerequisite before taking Electrical and Computer Engineering telecommunications and networking courses.
    • Concentrations are noted on the student’s transcript.

Post-Master's Certificate

Admission Requirements

Certificate Requirements

  • Six courses must be completed within three years.
  • Five of the six courses must be Computer Science ( courses, and at least two of these courses must be at the 700-level.
  • Only grades of B− or above can count toward the post-master's certificate.
  • Students are allowed to take one elective, subject to advisor approval, with the exception of students focusing on Bioinformatics, who are permitted to apply up to two Bioinformatics courses from the Krieger School of Arts and Sciences Advanced Academic Programs towards the certificate.
  • Tracks are not available for students pursing certificates.
  • All course selections are subject to advisor approval.
