Nationally recognized First Aid certificates may only be issued by Registered training organisations who are accredited on the National Training Information System (NTIS). Courses are based on the delivery and assessment of Unit's of Competency from various Training Packages. Most First Aid certificates are issued at one of three levels:

Provide Basic Emergency Life Support | Covering primarily life-threatening emergencies.

Apply First Aid | Covering all the aspects of training in "Provide Basic Emergency Life Support, as well as specialized training for treatment of burns, bites, stings, electric shock and poisons and the use of an AED. Apply First Aid must be re-accredited every three years to remain current for use in the workplace. Reaccreditation of the CPR component is generally required annually, although individual states set the specific requirements.

Apply Advanced First Aid | Covering advanced first aid, use of oxygen and automated external defibrillators and documentation. It is suitable for workplace First Aiders and those who manage First Aid facilities.

Other courses outside these levels are commonly taught, including CPR-only courses, Advanced Resuscitation, Remote Area or Wilderness First Aid, Administering Medications (such as salbutamol or the Epi-Pen) and specialized courses for parents, school teachers, community first responders or hazardous workplace first aiders. CPR Re-accreditation courses are sometimes required yearly, regardless of the length of the overall certification. Source: wikipedia
