Only need one category?
These half-day options include certification. They may be booked individually by candidates who hold the required current core certification and meet the relevant ACS entry requirements.
Optional kit for working life
Returning to ACS? Start with the kit you have.
If your working kit needs a refresh, compare what is already in your bag with the jobs you carry out. You may only need a replacement item.
