Pregnancy in Chemistry Labs:

UC Irvine does not discriminate against any student on the basis of pregnancy or pregnancy-related conditions. Absences due to medical conditions relating to pregnancy will be excused for as long as deemed medically necessary by a student’s doctor and students will be given the opportunity to make up missed work. Students needing accommodations can seek assistance from the Disabilities Services Center at or (949) 824-7494 or from the Title IX Office (the Office of Equal Opportunity and Diversity) at or (949) 824-5594.  

The Department of Chemistry and the Department of Environmental Health & Safety Risk Services ensure that each student’s exposure to hazardous chemicals falls within acceptable limits as determined by OSHA and Cal/OSHA.   However, if you are pregnant, there may be additional risks to consider and so we strongly encourage you to consult with your physician and the Disabilities Services Center at or (949) 824-7494 before undertaking work in the laboratory.

Concurrent Enrollment (formerly known as ACCESS UCI):

Beginning on a date that is TBD (date will be listed below), you may submit the Chemistry Concurrent Enrollment Form. Chemistry Concurrent Enrollment Forms are processed in the order that they are received.

If you meet eligibility criteria and course space is available:

You will be notified, via email, and asked to submit an additional Concurrent Enrollment Form at the front desk of 1102 Natural Sciences II.

  • Spring 2019 quarter: TBD 

Summer Session Policies:

The Chemistry Department enforces prerequisites during UCI Summer Session. Current UCI students that have taken the prerequisites at UCI will be able to enroll without additional clearance.

Students from outside UCI will need to provide transcripts demonstrating that they have met the prerequisites outlined in the UCI General Catalogue. You will be contacted for this documentation prior to the start of the course through email. 

Students who wish to enroll in a lab after the Summer Session has begun must recieve Deparmental approval by emailing Students may not enroll in a lab course after the Summer Session has begun if they have missed any of the lab sessions.
