IAED EMD is the certification for MPDS-based emergency medical dispatch. Candidates complete a 24-hour IAED-approved course and pass a closed-book multiple-choice exam with a score of at least 80 percent. Certification is valid for 2 years; recertification requires 24 hours of Continuing Dispatch Education (CDE) and an open-protocol exam, again at 80 percent. Content covers the four-part MPDS call flow (Case Entry, Key Questions, DLS, Case Exit), the 34 chief complaint protocols, determinant codes from OMEGA to ECHO, scripted PAIs/PDIs (Telephone CPR, choking, childbirth, naloxone, AED, bleeding control, hazmat), and QA fundamentals (AQUA, EMD-Q, ACE 20 Points).

1Which professional body administers the Emergency Medical Dispatcher (EMD) certification and maintains the Medical Priority Dispatch System (MPDS)?
A.International Academies of Emergency Dispatch (IAED)
B.National Emergency Number Association (NENA)
C.Association of Public-Safety Communications Officials (APCO)
D.National Highway Traffic Safety Administration (NHTSA)
Explanation: The IAED is the standard-setting body for EMD, EFD, EPD, and ETC certifications and is the steward of the MPDS protocols. Priority Dispatch Corp. publishes the materials and ProQA software, but certification is granted by IAED.
2Who originally developed the Medical Priority Dispatch System used by IAED-certified EMDs?
A.Dr. Jeff Clawson
B.Dr. Eugene Nagel
C.Dr. Norman McSwain
D.Dr. Peter Safar
Explanation: Dr. Jeff Clawson, while working as a Salt Lake City EMT and dispatcher in the late 1970s, developed the structured caller-interrogation and pre-arrival instruction system that became MPDS. He later co-founded what is now the IAED.
3An EMD candidate completes the required 24-hour EMD course. What minimum score must be achieved on the IAED certification exam to pass?
A.80 percent
B.70 percent
C.75 percent
D.90 percent
Explanation: IAED requires a minimum passing score of 80 percent on the closed-book multiple-choice EMD certification examination after completing the 24-hour approved course.
4How often must an IAED-certified EMD recertify, and what amount of Continuing Dispatch Education (CDE) is required during that cycle?
A.Every 2 years with 24 hours of CDE
B.Every year with 12 hours of CDE
C.Every 3 years with 36 hours of CDE
D.Every 2 years with 48 hours of CDE
Explanation: EMDs recertify every two years by completing 24 hours of approved Continuing Dispatch Education (CDE) and passing an open-protocol recertification examination at 80 percent or higher.
5In MPDS, what is the correct sequence followed on every medical call?
A.Case Entry, Key Questions, Dispatch Life Support (PAIs/PDIs), Case Exit
B.Dispatch, Key Questions, Case Entry, Case Closure
C.Key Questions, Pre-Arrival Instructions, Case Entry, Dispatch
D.Case Entry, Dispatch, Key Questions, Pre-Arrival Instructions
Explanation: MPDS structures every call as Case Entry, Key Questions, Dispatch Life Support (which includes Pre-Arrival Instructions and Post-Dispatch Instructions), and Case Exit. Dispatch is sent as soon as a chief complaint and address are confirmed, in parallel with continued interrogation.
6Which four Case Entry questions are asked verbatim at the beginning of every MPDS medical call?
A.Address, callback number, what's the problem, and patient's age/consciousness/breathing
B.Address, name of caller, patient's medications, and whether police are needed
C.Callback number, weather conditions, address, and patient history
D.Patient's name, social security number, address, and chief complaint
Explanation: MPDS Case Entry confirms the address, callback number, and chief complaint, then asks the patient's approximate age, consciousness, and breathing status to identify Fast Track conditions like cardiac arrest or unconscious-not-breathing.
7An MPDS determinant code reads 10-D-4. What does the letter 'D' represent?
A.The determinant level (Delta) indicating high-acuity, life-threatening response
B.The dispatch agency code
C.The dispatcher's certification level
D.A district code indicating geographic zone
Explanation: In a determinant code, the letter is the determinant level. Levels run OMEGA, ALPHA, BRAVO, CHARLIE, DELTA, ECHO from lowest to highest acuity. 'D' is DELTA — a high-acuity, life-threatening category warranting an advanced-life-support response.
8Within an MPDS determinant code such as 9-E-1, which level is reserved for the highest priority — typically requiring closest-unit response, including BLS first-responder activation?
A.ECHO
B.DELTA
C.CHARLIE
D.ALPHA
Explanation: ECHO is the highest determinant level, used when the patient is in or about to be in extremis. Closest-unit response, including BLS first responders, is typically launched. Example: 9-E-1 indicates cardiac arrest with workable resuscitation potential.
9Which determinant level in MPDS is used for incidents that are referable or that warrant a non-emergency or alternate-care response with no lights and siren?
A.OMEGA
B.BRAVO
C.CHARLIE
D.DELTA
Explanation: OMEGA-level determinants are used for situations that may be referred to nurse triage, alternate care, or a non-emergency response. They sit below ALPHA in acuity and exist on certain protocols, such as #26 Sick Person.
10An MPDS chief complaint protocol number identifies which of the following?
A.The specific clinical problem category being interrogated, such as protocol 6 for Breathing Problems
B.The unit type that will respond
C.The age range of the patient
D.The county dispatch zone
Explanation: Each of the 34 MPDS chief complaint protocols is numbered. Protocol 6 is Breathing Problems, 9 is Cardiac or Respiratory Arrest/Death, 10 is Chest Pain, 11 is Choking, 26 is Sick Person, and so on. The number defines the clinical interrogation set.

IAED EMD Study Tips from Top Performers

1Read the MPDS Principles of Emergency Medical Dispatch text or your course manual once cover to cover before timed practice — understanding the philosophy of structured interrogation makes the protocols easier to memorize.
2Build a 'protocol tree' flashcard set: chief complaint number, primary indications, top Key Questions, and characteristic determinants for each of the 34 protocols.
3Memorize the determinant level hierarchy (OMEGA, ALPHA, BRAVO, CHARLIE, DELTA, ECHO) and the chief complaints that have ECHO levels — those are the highest-acuity dispatches you must recognize fast.
4Practice scripted PAIs out loud: Telephone CPR (compressions only), Heimlich for conscious choking adults, childbirth, prolapsed cord knee-chest, naloxone administration, tourniquet placement, and eye irrigation.
5Drill the difference between PAIs and PDIs by listing two examples from each on the same protocol (e.g., Protocol 9 PAI = compressions; PDI = unlock the door).
6For QA questions, learn the AQUA deviation categories (minor/moderate/major), the ACE 20 Points headline standards, the ~3 percent random review threshold, and the difference between IAED ACE standards and NENA-STA-020.
7Practice Calltaker techniques — Persistence, Repetitive Persistence, and Hysterical Threshold management — using sample hostile-caller scripts; the exam tests recognition of these.
8Use a 90-day study plan: course weeks 1-3, protocol drilling weeks 4-6, PAIs and QA weeks 7-8, mixed timed practice weeks 9-12.

Frequently Asked Questions

What is the IAED EMD certification?

The Emergency Medical Dispatcher (EMD) certification, issued by the International Academies of Emergency Dispatch, is the credential for 9-1-1 medical telecommunicators using the Medical Priority Dispatch System (MPDS). It is earned by completing a 24-hour IAED-approved course and passing a closed-book multiple-choice exam at 80 percent or higher.

Who administers the EMD exam and the MPDS protocols?

The IAED is the certifying body and the protocol steward. Priority Dispatch Corp. publishes the MPDS materials and the ProQA software many centers use to deliver the protocol on the console.

What score do I need to pass the IAED EMD exam?

Candidates must score at least 80 percent on the multiple-choice EMD certification exam. The recertification exam (open-protocol) also requires 80 percent.

How long is the IAED EMD course?

The IAED-approved EMD course is 24 hours of instruction, which can be delivered in classroom, blended, or virtual formats depending on the provider.

How often must EMDs recertify?

EMDs recertify every 2 years by completing 24 hours of Continuing Dispatch Education (CDE) and passing the open-protocol recertification exam at 80 percent or higher.

What is the MPDS call flow?

MPDS organizes every medical call into Case Entry, Key Questions, Dispatch Life Support (which includes Pre-Arrival and Post-Dispatch Instructions), and Case Exit. Responders are dispatched as soon as the chief complaint and verified address are known.

What is a determinant code like 10-D-4?

The first number (10) is the chief complaint protocol (Chest Pain), the letter (D) is the determinant level (DELTA — life-threatening), and the second number (4) identifies the specific descriptor within that level. Suffixes can be appended to capture condition modifiers.

What is the difference between PAIs and PDIs?

Pre-Arrival Instructions (PAIs) are scripted, time-critical hands-on interventions like Telephone CPR, choking maneuvers, childbirth coaching, and naloxone administration. Post-Dispatch Instructions (PDIs) are non-critical safety/comfort directives such as unlocking the door, securing pets, and gathering medications.

What is ACE accreditation?

The IAED Accredited Center of Excellence (ACE) program recognizes communication centers that meet 20 specific standards of MPDS compliance, QA sampling, EMD-Q certification, training, and Medical Director oversight.

What is the role of an EMD-Q?

An EMD-Q is an IAED-certified quality-assurance reviewer who scores randomly sampled calls in AQUA software against MPDS compliance, classifying deviations as minor, moderate, or major and trending performance over time.
