Certification is not universally required but may be strongly preferred or required by many employers. CMA (AAMA) and RMA (AMT) are the most recognized credentials. Listing your certification status clearly — including exam pass date — helps employers quickly confirm eligibility for their specific requirements.

Create a skills section with two clear categories: Clinical Skills (phlebotomy, EKG, injections, vital signs) and Administrative Skills (scheduling, billing, EMR documentation, insurance verification). This structure allows ATS systems to match both types of keywords and shows hiring managers your full versatility.

Match the specialty's clinical language — pediatric clinics may want immunization administration and child-appropriate phlebotomy; cardiology offices may want EKG interpretation and Holter monitoring. Tailoring your clinical keywords to the specific specialty may improve match rates significantly.
