Introduction

The Radiation Therapy Professional Curriculum was developed by a committee representing a variety of program types from across the country. The American Registry of Radiologic Technologists^® (ARRT^®) and the Joint Review Committee on Education in Radiologic Technology (JRCERT) provided input to this revision to maintain continuity between the professional curriculum, accreditation standards and the certification examination.

The healthcare environment requires radiation therapy professionals to meet evolving clinical, organizational and fiscal demands. In particular, students must develop skills in areas such as information literacy, scientific inquiry, self-reflection and collaboration. Advances in technology and employer expectations require more independent judgment from therapeutic practitioners than ever.

This curriculum is divided into specific content areas that represent the essential components of an entry-level radiation therapy program. This document includes lists of learning objectives associated with each content area to serve as guidelines for programs. Faculty are encouraged to expand these fundamental objectives as they incorporate them into their curricula. Specific instructional techniques were intentionally omitted from this curriculum to encourage programs and educators to exercise greater freedom and creativity in instructional delivery. Programs are encouraged to reorganize the content and modify the objectives to meet their programmatic goals and needs.

The radiation therapy curriculum is based on the latest data and reflects the dynamic health care environment. This curriculum offers an educational foundation suitable for a baccalaureate degree program. The curriculum is designed with the flexibility to meet the needs of many communities, without compromising on the requirements of the JRCERT Standards and the ARRT examination.

Note: The general education and professional content areas of the curriculum are not split into specific courses. To preserve the flexibility of radiation therapy programs, content within each topic area may be integrated into various courses.

General Education

General education is the foundation for the future development of a therapeutic practitioner and provides the background knowledge to support continued professional development. General education content is designed to develop essential skills in communication, human diversity, scientific inquiry, critical thinking, and judgment. All these skills are required to perform the responsibilities of an entry-level radiation therapist. Knowledge gained from general education enhances the content of the rest of the radiation therapy curriculum.

Starting in 2015, the ARRT began requiring an associate degree to apply for the radiation therapy certification exam, eliminating the need for specific general education requirements in the radiation therapy curriculum. Because individual states, accreditation agencies, and educational systems have unique general education requirements, the content listed below is designed to serve only as a guideline for program development.

Postsecondary general education should be gained through courses that provide college credit and meet the general content areas listed below:

Mathematics and reasoning
- Demonstrate skills in analysis, quantification and synthesis.
- Apply problem-solving or modeling strategies.
Communication
- Write and read critically.
- Speak and listen critically.
- Collect, organize and present information.
Humanities
- Demonstrate respect for diverse populations.
- Define ethics and the role they play in personal and professional interactions.
- Critically examine personal attitudes and values.
Information systems
- Use computerized systems to acquire, transfer and store digital information.
- Use technology to retrieve, evaluate and apply information.
Social sciences
- Adapt communication to meet the cultural and psychological needs of others.
- Develop and exhibit leadership skills.
- Exercise responsible and productive social conscience.
Natural sciences
- Apply the scientific method.
- Make informed judgments about science-related topics.
- Define and use scientific vocabulary.

Expanded General Education Content

Mathematical knowledge can be expanded to include calculations for radiation treatment and protection, radioactivity and radiobiological functions.
Communication skills can be expanded to facilitate technical and scientific inquiry, analysis and dissemination of knowledge. This content will include the written expression of thoughts and observations derived from the critical thinking process. Additionally, this content will include the theory and practice of public speaking, development of informative and persuasive skills and the ability to tailor information and delivery to specific audiences.
Information systems skills can be expanded to radiation therapy simulation, information processing, treatment planning and treatment delivery.
Knowledge of human anatomy and physiology can be expanded to include correlation of anatomical landmarks to internal organs, in-depth examination of the lymphatic system and recognition of sagittal and coronal anatomical structures in cross-sectional views. This content can explore the processes by which tumors originate, grow, metastasize and alter the normal function of body systems. Terminology and organization of the human organism at the cellular, tissue and organ levels can be included. Additionally, the structure and function of human body systems can be covered in detail. A laboratory section is recommended for these topics.
General Physics content can be expanded to include the application of physical principles and laws, such as gravitation, electricity, magnetism, wave motion and thermodynamics as they relate to scientific disciplines and apply to radiation physics.
