When Training Falls Short: FDA Findings on GMP Training Deficiencies in 2025

Adequate training of personnel in the GMP-regulated environment is the basis of a compliant pharmaceutical quality system. Without properly trained staff, product quality, regulatory compliance, and patient safety cannot be ensured. Numerous GMP violations resulting in FDA Warning Letters (and EU Non-GMP Compliance Reports) are caused by a lack of GMP training.

National regulations around the world require sufficient employee training. 21 CFR 211.25, where the requirements for employee training in the US are laid down, explicitly requires that "each person engaged in the manufacture, processing, packing, or holding of a drug product shall have education, training, and experience, or any combination thereof, to enable that person to perform the assigned functions" (21 CFR 211.25(a)).

Compliance with this regulation is monitored during FDA inspections.

In 2025, the FDA has identified a significant number training deficiencies during inspections. The resulting Warning Letters highlight recurring deficiencies in personnel qualification:

• Rite-Kem Incorporated - January 2025

  Finding: "Your quality unit (QU) … failed to establish and follow written procedures (e.g.,..., CGMP training,...)."
• Cdymax India Pharma Private Limited - November 2025
  Finding: "Additionally, your corrective action of providing "refresher training for personnel on good laboratory practice" contradicted the investigation's own initial finding that the analyst was trained and qualified to perform the HPLC test according to your procedure."

The FDA's expectations for GMP training are outlined in the Warning Letters published in 2025. All employees involved in the manufacture, processing, packing, or holding of a drug product must be adequately trained and retrained. Training and retraining should be conducted on a regular basis by a qualified trainer. Training must be documented and the success of the training should be assessed.

The findings further indicate that inadequate employee training is a persistent problem and often the root cause of many other violations mentioned in FDA Warning Letters.
