2026 What Does a Home Health Occupational Therapist Do: Responsibilities, Requirements, and Salary

Most speech language pathology programs require applicants to complete a set of undergraduate prerequisite courses that provide a foundation in communication sciences, linguistics, psychology, and basic sciences. These requirements are based on standards set by the American Speech-Language-Hearing Association (ASHA) to ensure students are prepared for graduate-level clinical training.

Here are the common prerequisite courses you’ll need before applying to an SLP master’s program:

• Anatomy and Physiology of Speech and Hearing – Covers the biological structures involved in speech, language, and swallowing.
• Phonetics – Teaches transcription and analysis of speech sounds using the International Phonetic Alphabet (IPA).
• Speech and Hearing Science – Focuses on the acoustic, physiological, and perceptual aspects of speech and hearing.
• Language Development – Examines how language is acquired and develops across childhood.
• Introduction to Communication Disorders – Provides an overview of speech, language, and hearing disorders.
• Audiology or Hearing Science – Introduces hearing mechanisms and common hearing impairments.
• Statistics – Required by ASHA for evidence-based practice and research literacy.
• Biological Science – Typically a course in biology or human anatomy that relates to normal bodily functions.
• Physical Science – Usually a course in physics or chemistry, often emphasizing acoustics.
• Social/Behavioral Science – A psychology, sociology, or anthropology course to understand human behavior and communication contexts.

Some programs may also require linguistics or neurology-related coursework, while others allow flexibility if equivalent classes are completed. If your undergraduate degree is not in communication sciences and disorders (CSD), you can complete these prerequisites through a post-baccalaureate or speech language pathologist degree online program before applying to graduate school.

Most speech-language pathology (SLP) master’s programs require at least one 3-credit course in psychology or another social or behavioral science as part of the admission prerequisites. This aligns with ASHA’s requirement that all applicants complete coursework in the social and behavioral sciences to understand human behavior and development as they relate to communication.

While requirements vary by school, here’s a general guideline:

• Minimum Requirement: 3 credits (one semester course) in psychology, sociology, anthropology, or a related field.
• Preferred Coursework: Programs often recommend developmental psychology, child psychology, or lifespan development, as these subjects connect directly to language acquisition and clinical practice.
• Additional Credits (Optional): Some programs may prefer or accept 6 credits (two courses) if you plan to strengthen your background in human behavior or plan to pursue a research-heavy or pediatric-focused program.

If your transcript doesn’t clearly show a qualifying social science course, most programs allow you to take one online or at a community college before or during the application process. Always check individual program websites, as some specify the exact course titles or require a minimum grade (usually C or higher).

The best undergraduate majors for speech-language pathology (SLP) master’s programs are those that build a strong foundation in communication, science, and human development. While you don’t need a specific major to apply, certain degrees align more closely with graduate-level coursework and clinical practice.

Here are the most common and advantageous undergraduate majors for future SLP applicants:

• Communication Sciences and Disorders (CSD) – This is the most direct path. It includes all required prerequisite courses (phonetics, anatomy of speech, language development, audiology, etc.) and prepares you for a smooth transition into graduate school.
• Linguistics – Ideal for students interested in language structure, phonology, and syntax. You’ll still need to complete clinical prerequisites separately, but this major provides a strong academic base.
• Psychology – Focuses on cognition, behavior, and development—key areas in understanding communication and learning differences. Often requires additional SLP prerequisite coursework later.
• Education or Early Childhood Development – A good choice if you’re interested in school-based speech therapy. It helps you understand child development and learning environments.
• Biology or Neuroscience – Excellent for students interested in the medical or neurological aspects of speech-language pathology, such as swallowing disorders or brain injury rehabilitation.

If your degree is in another field—like English, nursing, or social work—you can still apply to SLP programs by completing post-baccalaureate or online prerequisite courses in communication sciences and related subjects.

Graduate programs care more about whether you’ve completed the required prerequisite courses and maintained a competitive GPA than about your exact major.

No, a communication sciences and disorders (CSD) degree is not required for admission to a master’s program in speech-language pathology (SLP). However, it’s the most straightforward and efficient path because it already includes nearly all the prerequisite courses that graduate programs require.

If you earned your bachelor’s degree in another field—such as psychology, linguistics, education, or biology—you can still apply to SLP school. You’ll just need to complete the required prerequisite courses before enrolling in the graduate program. These typically include:

• Phonetics
• Anatomy and Physiology of Speech and Hearing
• Speech and Hearing Science
• Language Development
• Introduction to Communication Disorders
• Statistics, biological science, physical science, and social/behavioral science (per ASHA requirements)

Many universities offer post-baccalaureate (post-bacc) or accelerated SLP programs online specifically designed for non-CSD majors. These programs usually take one to two years and prepare you to meet both ASHA and individual school prerequisites.

In short, a CSD degree isn’t mandatory—but having one saves time and ensures you’re academically prepared for the rigors of graduate study in speech-language pathology.

Non-CSD (Communication Sciences and Disorders) majors can complete the required speech-language pathology (SLP) prerequisites through post-baccalaureate (post-bacc) or online leveling programs offered by many universities. These programs are designed for students who hold a bachelor’s degree in another field—such as psychology, linguistics, biology, or education—but want to pursue a master’s in speech-language pathology.

Here’s how the process typically works:

Enroll in a Post-Baccalaureate or Leveling Program

• These programs offer all the prerequisite courses required for SLP admission, such as phonetics, anatomy of speech and hearing, language development, audiology, and speech and hearing science.
• Duration: Usually 12 to 24 months, depending on your previous coursework and whether you study full- or part-time.

Choose Online or In-Person Options

• Many universities offer fully online SLP prerequisite programs, which are flexible for working professionals or career changers.
• Others have on-campus programs for those who prefer classroom interaction and access to labs.

Verify ASHA and School Requirements

• Each SLP graduate program sets its own prerequisites. Always check that the post-bacc courses you take meet ASHA’s academic standards and your target school’s admission requirements.

Maintain Strong Grades

• Most SLP programs require at least a 3.0 GPA in prerequisite courses. Strong academic performance shows you can handle the graduate-level rigor of an SLP master’s program.

Earn a Certificate (Optional)

• Some post-bacc programs award a certificate in communication sciences and disorders, which strengthens your graduate application and confirms completion of all prerequisites.

Many universities—such as Emerson College, the University of St. Augustine, and Eastern New Mexico University—offer reputable online SLP prerequisite programs for non-CSD majors.

Completing post-baccalaureate (post-bacc) prerequisites for speech-language pathology typically takes 12 to 24 months, depending on your academic background and course load. Students who already have some overlapping credits in areas like linguistics, psychology, or biology may finish faster—often within a year if studying full-time. Programs designed for working professionals or career changers usually offer part-time and online options, allowing you to spread courses over two years or more.

The exact length also depends on the number of prerequisite courses required by your target SLP programs. Most post-bacc tracks include around 8 to 10 core courses, such as phonetics, anatomy of speech and hearing, and language development. If you’re missing foundational sciences—like statistics or physics—you may need additional semesters. Some schools let students complete prerequisites on a rolling basis, while others follow a set cohort schedule, which can influence the timeline.

Many students use this period to strengthen their graduate applications by gaining observation hours, volunteer experience, or exposure to clinical settings. Finishing your prerequisites efficiently—while maintaining a strong GPA—can make you a more competitive candidate when applying to accredited SLP master’s programs.

The cost to complete post-baccalaureate prerequisites for a master’s in speech-language pathology (SLP) can vary substantially depending on the number of courses you need, the institution’s tuition rates, whether the courses are taken online or in-person, and whether you’re in-state or out-of-state. According to one source, students looking at SLP post-bacc programs should expect costs in the ballpark of $300-$500 per credit unit, which typically translates to $900-$1,500 per class. 

For example, the online post-bacc program at University of Florida charges $280 per credit hour for in- and out-of-state students. Meanwhile another list shows programs ranging from around $12,000 to over $24,000 total depending on total units required and program structure. 

When budgeting, consider also additional costs beyond tuition: technology fees, materials/supplies, course fees, and sometimes travel or on-site requirements if hybrid or in-person. If you’re taking only a few prerequisites, the cost may be relatively modest; if you’re completing a full post-bacc leveling certificate with many courses, the cost could approach the lower end of graduate-school tuition.

The American Speech-Language-Hearing Association (ASHA) is the national professional organization that sets academic and clinical standards for speech-language pathologists and audiologists in the United States. To become a certified SLP, applicants must meet ASHA’s educational and clinical requirements, which begin with completing specific prerequisite coursework before entering a graduate program.

ASHA requires all speech-language pathology master’s students to have completed undergraduate coursework in the following four areas:

• Biological Science – Typically a course in biology or human anatomy and physiology.
• Physical Science – Usually a physics or chemistry course, with acoustics preferred.
• Social/Behavioral Science – A course in psychology, sociology, anthropology, or a related field.
• Statistics – A standalone statistics course focused on quantitative methods (not research methods).

In addition to these general education areas, most graduate programs—following ASHA’s academic standards—expect applicants to have completed core communication sciences and disorders (CSD) prerequisites such as phonetics, speech and hearing science, language development, and anatomy of speech and hearing.

These requirements ensure that all entering students have the foundational knowledge necessary for advanced clinical and scientific study in speech-language pathology.

Yes, most ASHA-accredited speech-language pathology (SLP) programs accept online prerequisite courses, as long as they are taken from a regionally accredited college or university. What matters to graduate admissions committees is the content and accreditation of the course—not whether it was delivered online or in person.

However, there are a few key points to keep in mind:

• Accreditation matters most. The online course or post-bacc program must come from a regionally accredited institution. ASHA does not approve or accredit specific prerequisite courses, but graduate schools verify that coursework meets ASHA’s academic standards.
• Course content must match requirements. Programs often ask for detailed syllabi or course descriptions to ensure your online coursework covers topics such as phonetics, speech and hearing science, or language development.
• Grades and credits count equally. Online credits carry the same weight as on-campus ones if they appear on an official transcript with letter grades and credit hours.
• Check each program’s policy. Some schools may specify whether they accept online labs or require certain science prerequisites to be completed in person.

In short, yes—online SLP prerequisite courses are widely accepted, provided they’re equivalent in rigor, come from an accredited institution, and meet the individual graduate program’s standards.

Yes, prerequisite requirements differ among SLP graduate schools, even though most follow the general academic standards outlined by the American Speech-Language-Hearing Association (ASHA). Each university sets its own admission criteria and may interpret or expand upon ASHA’s core recommendations.

Nearly all programs require foundational coursework in areas such as phonetics, anatomy and physiology of speech and hearing, language development, speech and hearing science, and audiology. However, some schools may require additional or more specialized courses—like neurology for communication disorders or research methods—while others are more flexible.

The main differences usually involve:

• Number of prerequisite courses required (anywhere from 5 to 10).
• Timing of completion—some programs let you apply while finishing prerequisites, while others require them to be completed before admission.
• Acceptance of online or transfer credits.
• Minimum grade or GPA requirements in prerequisite coursework.

Because of these variations, it’s best to review each school’s SLP admissions page or contact the graduate admissions office to confirm which courses they require. This ensures your coursework aligns with both ASHA standards and the specific program’s prerequisites.

Most programs require a minimum of 25 guided observation hours before beginning clinical practicum. Some post-baccalaureate and undergraduate programs include these hours as part of coursework, while others allow you to complete them independently under ASHA-certified supervision.
