on completion of the cat examinations, students will be automatically transferred onto the acca professional scheme register, unless they indicated on the cat registration form that no such transfer should take place. transfer is not dependent upon obtaining any cat practical experience and all transferred students are awarded exemption from professional scheme papers 1.1,1.2 and 1.3. there is no additional registration fee to pay, nor will there be any charge for the exemptions awarded for part 1 papers.
cat students who are automatically transferred to the professional scheme are issued with a new student id card and number, and have the opportunity to take acca examinations at the next available session. students completing cat examinations at the june exam session, for example, can tak acca part 2 papers from december. cat students who indicated at the time of registration that they did not wish for an automatic transfer to the professional scheme, can still opt for the automatic transfer if a written request is submitted to acca connect before sitting the final cat examinations.

以上摘自2005年8月份的acca學員雜志——《student accountant》

學員在學完cat后，自動轉為acca的學員，除非學員在注冊成為cat學員時選擇不要自動轉會。從cat成功轉為acca的學員自動獲得acca第一階段（3科）的免試，不需交任何額外的費用，也無需交繳附加的注冊費。（其它情況的免試均交繳與考試費金額等同的免考費）

cat學員自動轉為acca的學員后，會獲得一個新的注冊卡和注冊號，學員在下一次的考試中即可參加acca的考試。如：學員在6月份通過cat所有科目的考試，那么學員在同年12月份即可參加acca第二階段的考試。在注冊時選擇不自動轉為acca的學員，在參加cat最后幾科考試之前，也可以給acca寫申請，選擇為自動轉為acca。
