RLHF (Reinforcement Learning from Human Feedback) is the process of training AI systems using expert human judgement. In clinical RLHF, healthcare professionals review, rate, and correct AI-generated medical content to make AI safer and more accurate.

Who can take this training?

Our training is designed for UK-registered healthcare professionals — doctors, nurses, pharmacists, researchers, academics, and allied health professionals. You need clinical expertise but no technical or AI background.

Do I need medical qualifications?

Yes. Our training is specifically for registered healthcare professionals. Your clinical knowledge is what makes you valuable as an RLHF evaluator — you bring the domain expertise that AI companies need.

How long does training take?

Foundation Training takes about 45 minutes. Calibration is five short cases most days, about four minutes, across eight kinds of task. There is no long session and no pass mark. Optional specialist deep-dives are coming later and won't be required for certification.

Is the training free?

Yes, all training on EnterTheLoop is completely free. We invest in your training because better-trained evaluators produce higher-quality RLHF work, which benefits everyone — candidates, employers, and patients.

Training Academy

Free RLHF training, built for clinicians.

Start with a foundation course, then calibrate your judgement in five short cases a day, on cases written for your own profession. Your reliability goes on record, then we match you to paid clinical AI evaluation work. No technical background needed, and completely free.

The pathway

How training works.

One route, four stages, paced across as many days as you like. A foundation course, daily calibration on cases written for your profession, and a reliability score on record, then we match you to paid clinical AI work. No AI background required; the same route runs for every profession.

Calibration

Calibration.

After Foundation, calibration runs as a short daily loop rather than a single sitting. Your confidence is scored against your accuracy, week by week, on cases from your own profession.

Most days · ~4 min

The loop

Five short cases, most days, about four minutes. You read a case, decide, rate your confidence, and say why.

Eight kinds of task, a few at a time
A decision, a confidence rating, and a reason on every case
Scored against a key signed by clinicians in your profession
