CPD (Continuing Professional Development) Calculation is the process of determining the number of CPD credits or hours earned through learning and professional activities. The exact calculation depends on the requirements of the relevant professional body or accrediting organization, but a common approach is as follows:
| Activity | Typical CPDlue |
| 1 hour of structured training / workshop | 1 CPD credit |
| 1 hour of webinar or seminar | 1 CPD credit |
| Conference attendance | Based on actual learning hours |
| Online course completion | Credits equal to approved learning hours |
| Teaching or presenting | Often awarded additional credits, depending on policy |
| Publishing a research paper | Fixed credits as determined by the accrediting body |
| Self-directed learning | Usually calculated by documented study time |
Basic Formula
CPD Credits = Total Approved Learning Hours * Credit Multiplier
Understanding
- 1 hour of learning = 1 CPD credit
- 30 minutes = 0.5 CPD credits
- 90 minutes = 1.5 CPD credits
- 8 hours = 8 CPD credits
Example Calculations
| Activity | Hours | CPD Credits |
| Workshop | 3 | 3 |
| Webinar | 1.5 | 1.5 |
| Online course | 5 | 5 |
| Conference session | 6 | 6 |
| Total | 15.5 | 15.5 |
Annual Example
If a professional completes:
- 10 hours of workshops
- 8 hours of webinars
- 12 hours of online courses
Then:
Total CPD = 10 + 8 + 12 = 30 CPD credits (assuming 1 credit per hour).
If you are creating a CPD provider or accreditation framework, you can also use a weighted model, for example:
| Activity | Calculation |
| Attending training | 1 credit per hour |
| Delivering a lecture | 2 credits per hour taught |
| Publishing a peer-reviewed article | 10–20 credits |
| Poster presentation | 5 credits |
| Conference presentation | 8–15 credits |
