Common Respiratory Therapy Prerequisite Requirements

Requirements vary by program, but most associate and bachelor's (BSRC) RT programs draw from this set.

Anatomy & Physiology I & II

The two-semester sequence is required by nearly every RT program — usually with lab.

Microbiology

Commonly required with lab; central to infection control and patient care.

General Chemistry

Often required to understand gas exchange and medication chemistry.

College Math / Algebra

Supports dosage and ventilator calculations; some programs accept statistics.

English Composition

Documentation and case-report writing make composition a near-universal requirement.

Speech / Communication

Patient communication is essential; many programs require an oral-communication course.

General Psychology

A frequent social-science requirement supporting patient interaction.

Medical Terminology

Required or strongly recommended — the language of every clinical rotation.

Physics (BSRC programs)

Bachelor's-level RT programs frequently add introductory physics with lab.

Always confirm your specific program's list and recency rules. Our advisors can help you map them to the right courses.

Find the Right Courses for Your Path

Choose where you are in your respiratory therapy journey.

The core science gateway courses required by virtually every respiratory therapy program — all offered with lab where programs require it.

BIO 270

Human Anatomy & Physiology I w/ Lab

First semester of the required A&P sequence — the single most important RT prerequisite.

BIO 275

Human Anatomy & Physiology II w/ Lab

Second semester covering cardiovascular and respiratory systems central to RT practice.

BIO 210

Microbiology w/ Lab

Commonly required for RT admission; foundational for infection control.

CHEM 151

General Chemistry I w/ Lab

Atoms-first introduction; the default chemistry entry point for RT applicants.

CHEM 152

General Chemistry II w/ Lab

For programs requiring the full two-semester general chemistry sequence.

EXSS 170

Medical Terminology

The clinical vocabulary required or recommended across RT programs.

The general-education requirements RT programs pair with the sciences — composition, math, communication, and social science.

ENG 101

English Composition I

Near-universal requirement supporting clinical documentation and reports.

ENG 102

English Composition II

Second-semester composition required by some programs.

MATH 107

College Algebra

Satisfies the math gate at most RT programs.

MATH 220

Elementary Statistics

Accepted in place of algebra by many programs; useful for evidence-based practice.

COMM 200

Interpersonal Communication

Satisfies the oral-communication / speech requirement.

PSY 190

General Psychology

The standard introductory psychology course RT programs name.

SOC 110

Principles of Sociology

Satisfies the social-science requirement at programs that prefer sociology.

Bachelor's-level (BSRC) respiratory programs often require a heavier load — including introductory physics — on top of the science core.

PHY 115

Introduction to Physics I w/ Lab

The physics entry point for bachelor's RT programs that require it.

PHY 116

Introduction to Physics II w/ Lab

For programs requiring the full physics sequence.

MATH 220

Elementary Statistics

Frequently required at the bachelor's level for evidence-based coursework.

CHEM 151

General Chemistry I w/ Lab

Required science foundation carried into the BSRC curriculum.

BIO 275

Human Anatomy & Physiology II w/ Lab

Upper-division programs often require the complete A&P sequence.

PSY 190

General Psychology

A common social-science requirement in bachelor's RT degree plans.

RT admission is competitive — many programs rank applicants by prerequisite GPA. Retake a key science course to strengthen your application, or refresh a prerequisite that has expired.

BIO 270

Human Anatomy & Physiology I w/ Lab

The most-retaken RT prerequisite — a higher A&P grade can move a borderline application.

BIO 275

Human Anatomy & Physiology II w/ Lab

Refresh an expired A&P II credit or improve your science GPA.

BIO 210

Microbiology w/ Lab

Retake microbiology to satisfy recency rules or raise your science GPA.

CHEM 151

General Chemistry I w/ Lab

A strong chemistry grade improves the science GPA programs weigh most heavily.

Respiratory Therapy Prerequisite FAQs

Yes. Our prerequisite courses are delivered online and self-paced through Upper Iowa University, a regionally HLC-accredited institution. Most RT programs require coursework from a regionally accredited college, which is exactly what our partnership provides. Always confirm acceptance with your specific program.

Requirements vary, but most programs draw from Anatomy & Physiology I & II, Microbiology, General Chemistry, College Math or Statistics, English Composition, Speech/Communication, General Psychology, and Medical Terminology. Bachelor's-level (BSRC) programs frequently add introductory physics. Check your program's published list for specifics.

Possibly. Many RT programs require science prerequisites to have been completed within roughly five years of application. If your A&P or microbiology credit has expired, you can refresh it here quickly and on your own schedule rather than repeating a full semester elsewhere.

Most programs require a minimum prerequisite GPA — roughly 75% want a 3.0 or higher — and many rank applicants by their prerequisite grades because seats are limited. Retaking a key science course to earn a stronger grade is one of the most direct ways to improve a competitive application.

Courses are self-paced with monthly start dates. Many students complete a single course in as little as 2–3 weeks, though you can take the time you need within the enrollment period.

Our courses are regionally accredited and designed to transfer. Because acceptance is ultimately determined by your specific program, we recommend confirming with its registrar — and our advisors can help you map your program's requirements to the right courses.
