ACVREP COMS cheat sheet

O&M instruction addresses two linked constructs: orientation (using senses and environmental information to establish and maintain position relative to surroundings) and mobility (safe, efficient, and independent movement through the environment).

Core O&M body of knowledge domains include concept development, sensory/perceptual skills, spatial and environmental awareness, orientation systems, mobility skills and techniques, and the use of mobility tools and assistive technology.

Human guide technique: the traveler grasps the guide's upper arm just above the elbow, stands a half-step behind and to the side, and remains directly behind the guide when passing through narrow spaces.

Long cane technique fundamentals include the pencil grip, hand centered near midline, arc width roughly one inch beyond each shoulder, and rhythmic touch technique with the cane tip contacting the ground on each side of the body.

Diagonal cane technique is used for detecting overhead obstacles and for travel in familiar, reduced-complexity areas; constant-contact technique is used where surface changes and drop-offs must be detected continuously.

Protective techniques (upper-hand-and-forearm and lower-hand-and-forearm) are used to detect obstacles at head, chest, and waist level when moving without a cane or in unfamiliar indoor spaces.

Systematic search patterns (e.g., perimeter, grid, and spiral searches) are taught for locating dropped objects and for reestablishing orientation after becoming disoriented.

Orientation cues are classified as auditory, tactile, olfactory, kinesthetic, and visual; instruction sequences generally move from familiar to unfamiliar environments and from simple to complex routes.

Mobility instruction incorporates route planning, street-crossing analysis (signal type, traffic flow, and intersection geometry), use of public transportation, and problem-solving for unexpected situations.

ACVREP certification is a voluntary, non-governmental credential that attests an individual has met established professional standards; it is distinct from state licensure, which is a legal requirement to practice.

The Academy for Certification of Vision Rehabilitation and Accessibility Professionals (ACVREP) administers the Certified Orientation and Mobility Specialist (COMS) credential among its certification programs.

Eligibility for the COMS credential typically requires completion of an approved O&M personnel preparation program (or equivalent), supervised internship/practicum hours, and passing the certification examination.

The COMS examination is competency-based and covers the O&M body of knowledge, including sensory/perceptual skills, mobility techniques, orientation systems, and professional practice.

Certification cycles are time-limited; certificants must renew on a defined schedule and meet continuing education requirements to maintain the credential.

ACVREP publishes a Candidate Handbook and certification policies that define eligibility, application procedures, examination administration, and appeals; candidates should consult the current official documents for exact requirements.

Certificants are responsible for maintaining current contact information and for reporting changes that affect certification status to the certifying body.

Reciprocity and reciprocity-like pathways may exist for individuals holding comparable credentials; the certifying body determines acceptance on a case-by-case basis under its published policies.

Ethical practice requires placing the safety and welfare of the consumer first, including informed consent for assessment, instruction, and use of mobility devices.

O&M specialists must maintain confidentiality of consumer information, disclosing it only with consent or as required by law (e.g., suspected abuse, imminent risk of harm).

Practitioners must practice within their scope of competence and refer to other professionals (e.g., low vision therapists, rehabilitation teachers, medical providers) when needs fall outside O&M expertise.

Informed consent includes explaining the purpose, risks, benefits, and alternatives of O&M instruction, including the inherent risks of independent travel.

Dual or multiple relationships that could impair professional judgment or exploit the consumer should be avoided; when unavoidable, they must be managed transparently.

Accurate documentation and billing practices are ethical obligations; falsifying records or misrepresenting services constitutes misconduct.

Respect for consumer autonomy and dignity includes honoring cultural, linguistic, and personal preferences and avoiding paternalistic decision-making.

Conflicts of interest (e.g., financial interest in a device or vendor) must be disclosed and managed so they do not influence recommendations.

Recertification is generally required on a multi-year cycle; certificants must complete a specified number of continuing education (CE) units or hours within each cycle to maintain the credential.

CE activities typically include approved workshops, conferences, academic coursework, and professional presentations; the certifying body determines which activities qualify and how units are calculated.

Documentation of CE activities (certificates, transcripts, attendance records) must be retained and produced upon audit or renewal.

Some cycles require specific content areas (e.g., ethics or professional practice) in addition to general CE hours; check the current recertification policy for category requirements.

Failure to complete recertification requirements by the deadline may result in lapsed or suspended certification and may require reinstatement procedures, including fees or additional requirements.

Certificants should verify CE provider approval status before counting an activity toward recertification, since unapproved activities may not be accepted.

Recertification policies, deadlines, and unit requirements are subject to change; the current official handbook and website are the authoritative sources.
