Upgrading from the TAE40116 to the TAE40122 Certificate IV in Training and Assessment involves completing additional units and possibly undergoing assessments to bridge any gaps between the two qualifications. Here are the main steps and considerations for this upgrade:

Units of Competency: The TAE40122 includes 12 units (6 core and 6 elective), compared to the 10 units in TAE40116. Some units may be eligible for credit transfer if they are equivalent to units already completed in TAE40116. For example, units like TAEDEL402 can be credited towards TAEDEL412​ (Plenty Training)​​ (AIM Australia)​.

Gap Training and RPL: Recognized Prior Learning (RPL) can be utilized to assess the skills and knowledge you've already acquired. This may reduce the number of additional units you need to complete. Courses typically offer gap training through online modules, workshops, or self-paced learning to cover the new or updated content​ (Fortress Learning)​.

Delivery Methods: Many training organizations offer flexible delivery methods, including online courses, self-paced learning, and recorded webinars. This flexibility allows you to complete the upgrade at your own pace and convenience​ (Plenty Training)​​ (Fortress Learning)​.

Cost: The cost for upgrading varies. Some providers charge around $1500 to $1650, depending on whether you choose a full payment or a payment plan. This fee usually covers access to all necessary learning materials and assessments​ (Fortress Learning)​.

Validity and Transition Period: The TAE40116 will remain valid during the transition period, and both TAE40116 and TAE40122 are currently recognized qualifications. However, upgrading to TAE40122 ensures you have the most current qualification, which may be preferred by employers​ (Aveling | RTO 50503)​.

For specific details and to determine your eligibility for credit transfers or RPL, it's recommended to contact the training provider directly. They can provide personalized guidance based on your previous qualifications and experience.
