How to Become a NABL Auditor?

NABL auditors (assessors) are highly respected professionals in the diagnostics and testing industry. NABL assessors help ensure that laboratories across India maintain high quality and accuracy as per international standards.

This is how you can become a NABL assessor:

Who Is a NABL Auditor or Assessor?

A NABL assessor is a person who evaluates laboratories against relevant accreditation criteria and technical specifications. They are also known as a NABL auditor.

NABL stands for National Accreditation Board for Testing and Calibration Laboratories. It is one of the constituent boards of the Quality Council of India (QCI).

NABL assessors assess the competency of the staff, quality management system and supporting documentation.

The standard for medical laboratories is ISO 15189:2022.

NABL assessors may have to evaluate:

  • The laboratory quality management system.
  • Test procedures, technical competence and the records of calibration and maintenance of equipment.
  • Internal quality control and external quality assessment
  • Training of staff and other records.

How to Become a NABL Auditor?

Talented individuals who wish to be NABL assessors should go through the official process of NABL assessor training.

1. Eligibility

As per NABL's published criteria, you should be within the age range of 38 to 55 years. If you are applying for Medical Testing Laboratories, you shall need to have a postgraduate degree in a relevant medical discipline or hold a Ph.D. in a relevant science discipline. You must also have a minimum of 10 years' experience working in a clinical laboratory setting, including a minimum of 5 years' experience working in a supervisory or higher position. You will also need to choose an area of assessment based on the above criteria.

2. Knowledge of Relevant Standards

Anyone working in testing and calibration laboratories must have knowledge of ISO/IEC 17025:2017. Those from the medical lab field must be familiar with the requirements of ISO 15189:2022.

3. Apply for NABL Assessor Training

Eligible candidates need to apply for the official NABL Assessor Training through the official website of NABL.

During the application process, candidates will have to provide their qualifications, employment history, and professional details.

NABL shortlists candidates as per its requirements and whether it is able to locate a suitable subject matter expert.

4. Complete NABL Assessor Training

NABL conducts a training workshop to cover the following:

  • laboratory management system and assessment of clinical laboratory
  • access and use of resources by assessors
  • principles of auditing
  • observation of audit activities
  • writing nonconformity reports
  • reviewing assessment findings
  • interview techniques
  • writing assessment reports
  • documentation
  • openings and closings of assessment meetings

5. Pass NABL Assessment

After training, candidates need to take an NABL assessment to become an approved NABL assessor.

Candidates need to pass the written test conducted by NABL to qualify as assessors at the end of the assessor training course.

Successful completion of the training will be considered at the time of empanelment of a candidate as a NABL assessor.

Just completion of training does not make a candidate a NABL assessor.

Step 6: NABL Assessor Empanelment

Candidates who fulfill the said requirements may be considered for empanelment by NABL.

NABL assesses the person's characteristics required to perform assessment functions.

People selected for empanelment are required to enter into a contract with NABL.

Only upon fulfillment of all the requirements of selection and empanelment by NABL, a professional becomes an NABL assessor.

Mandatory NABL Assessor Training

NABL organizes assessor training for professionals in different fields of accreditation.

These include training of assessors of medical laboratory (ISO 15189), testing and calibration (ISO/IEC 17025), proficiency testing (ISO/IEC 17043) and reference material (ISO 17034) laboratories. Also, training of Biobank assessors (ISO 20387) is organized.

Training is defined based on the candidate’s technical background.

It is important to understand that NABL's official assessor training is not the same as a general ISO 15189 training or internal auditor training.

General training is helpful for professionals in enhancing their knowledge, but in itself does not make a candidate a NABL assessor.
