Provide a very large budget for formal training courses as well as many internal free courses. 5 year graduate program acts as sort of long term training course as graduates must meet a matrix of experience / criteria to graduate. Great culture for continuous learning, supervisor almost always supports any training opportunity / idea.
The training budget for graduates is quite generous allowing for attending any training you may want to in a year. The internal training is targeted and allows development in specific business areas. For example, the Heat Exchanger SME (Subject Matter Expert) ran a great workshop where he taught the fundamentals of heat exchangers and how to interpret performance and control them via live data.
lots of training budget and flexibility to do what you would like/find interesting
