The Honours Integrated Science (iSci) program limits enrollment to approximately 60 students per year and admission is by selection. Achieving the published minimum GPA requirements does not guarantee admission.

Students must have applied to the Integrated Science Program at McMaster University FIRST through the Ontario University Application Centre (OUAC) website. 

A mandatory iSci Supplementary Application must then be completed by all applicants.

To access and submit the Supplementary Application, you will need a valid MacID and password. Your MacID credentials will be available to you via email – approximately one week after submitting your OUAC application and payment. Please refer to the email titled “Next Steps Regarding your McMaster Application” for activation instructions. Please allow 30 minutes after activating your MacID to access the supplementary application.
Note: add ‘’ to your MacID to assist with logging into the application. If you have not yet received your MacID, please reach out to the Student Recruitment Team.If you need support activating your Mac ID, please reach out to University Technology Services (UTS).

Please note that use of generative AI tools in this application process is strictly prohibited. If found, appropriate charges will be brought forward to university officials in accordance with applicable university policies.

Expandable List

The Integrated Science Program (iSci) within the School of Interdisciplinary Science (SIS) strives to be an accessible, supportive, and inclusive community. As part of our efforts to acknowledge and minimize systemic and structural barriers in the program, we have introduced an Equitable Admissions for Black Applicants (EABA) process for our Level 1 applicants as part of the mandatory supplementary application. The purposes of this process are to reduce barriers that might discourage Black-identifying applicants from applying to the iSci program, and to mitigate the potential for unconscious bias to influence evaluation of supplementary applications.

The EABA is open to applicants who self-identify as Black (including Black African, Black Caribbean/West Indian, Black North American, Black/Afro-Latinx, multi-racial students who have Black ancestry that they identify with, and other Black identities).

This is an optional application stream for Black applicants.

To learn more about the process and associated resources, please read our Frequently Asked Questions.

To be considered for admission to the Integrated Science Program, students must have the following qualifications.

Completion of High School Diploma including the following Grade 12 U/M requirements:

  • English (ENG4U)
  • Advanced Functions (MHF4U)
  • Calculus & Vectors (MCV4U)
  • Two of: Biology (SBI4U), Chemistry (SCH4U), Physics (SPH4U)
  • One additional 12 U/M course

Students are strongly encouraged to take all three Grade 12 U science courses (Biology, Chemistry and Physics)

If you are an out-of-province or international student, visit the Office of the Registrar for entrance requirements specific to your province or country.

The Supplementary Application is required for all applicants.

Admission to the iSci Program is limited and by selection only. All iSci Program applicants are required to provide additional information on a Supplementary Application form, which is reviewed by the iSci Admissions Committee.

The purpose of the Supplementary Application is to help us learn more about you, why are you interested in iSci, and to try to ascertain whether the program is suited to you. We aim to identify highly-motivated, well-rounded students with an interest in all fields of science — students with strong communications skills, students who are excited about scientific research, and students who can think creatively about scientific issues. There is no formula for a ‘good’ Supplementary Application. Be honest! Be yourself!

Admission decisions for iSci are made in the spring and successful applicants will be notified of their offer of admission towards the beginning of May. Best of luck to all students who apply.

All students applying to Integrated Science I program must complete both the iSci Supplementary Application and the OUAC application (OUAC code: MIS).

If you have any questions, please email


ISCI for a day Visits (January – March)

The best way to know if iSci is the program for you is to visit!  Take advantage of our iSci for a Day Program:

Prospective student’s will be matched up with a first year iSci student ambassador with similar interests who will host them for the day. Visits will normally start in the morning before the first class. The iSci host and prospective student will make arrangements to me at a specific time and location, and the visit would then continue throughout the day to experience first year classes and/or labs along with McMaster campus.

Registration for the “iSci for a day” program is now closed for the 2023/ 2024 Academic Year. Watch for the program to start again in the 2024/2025 Academic Year.

We look forward to seeing you at May at Mac, or other future recruiting events.
