Continuous Professional Development, or CPD as it is more commonly known, has one basic proposition: Improvement. The teacher has the option of either passively waiting for someone else (the employer) to committ resources to CPD, or the teacher takes the initiative and actively seeks out CPD opportunities.
One might take the position that if the employer wants the teacher to improve, then the employer will make the necessary resources available. The “resources” referred to are time, materials, and money.
The teacher would receive pay for the time they are investing in learning. Books, travel costs, and any fees would be paid for by the employer. However, to be honest, in Chile very few teachers find themselves in this utopian situation.
