The partnership will see the bodies combine forces on new training qualifications, training delivery methods such as new e-learning platforms, and educational aids.
An ultimate guide for Personal Licence Holders in Scotland will be the first project to result from the new alliance. It will be applicable to individuals studying for their first licence qualification as well as all existing licence holders, who, because of new laws are now required to take refresher training before 2015, and every five years thereafter.
Tim Hulme, chief executive of the BII, said: "As leading providers of professional qualifications and training, the alliance will deliver huge benefits to our industry, so it's an exciting development for all."
The BII-CPL collaboration is also working on the development of a new e-learning platform for BII's Pre-Entry Awareness Training programme, PEAT, which will be available from October 2013.
Daniel Davies, chief executive of CPL, explained: "PEAT is an exciting collaborative project for CPL and BII because it is mandatory training for those wishing to take on a lease or tenancy.
"This is the first step in the development of a complete e-learning solution which will make available a suite of e-learning courses to the whole of the licensed retail sector. These courses will cover a range of subjects including compliance and due diligence issues such as age verification, craft training in things like coffee skills and the perfect serve, as well as 'soft skills' such as customer service."
