Since Jon Kabat-Zinn first introduced a contemporary, secularized application of mindfulness for the relief of pain and stress in physical health-care settings, there has been a significant and rapid expansion of the range of mindfulness-based programs (MBPs) designed for various health care, education, workplace, and other settings. As is common with developing programs, these often run ahead of carefully considered and researched effectiveness evaluations. This raises questions of how to best train mindfulness teachers to skillfully facilitate such interventions while minimizing the potential for harm. In this article, we describe the work of an international group of senior teacher trainers who met to develop guidelines on the ethics and standards for teacher trainers and their training pathways. In this article, we will define MBPs; describe the process by which these international guidelines were developed; and share details of the collaborative team who made up the international network that worked on them. We offer these guidelines as “living documents” that specifically set out: (1) ethical standards for mindfulness teachers and trainers; (2) criteria and standards for teacher trainers; and (3) criteria and standards for training pathways. As “living documents,” these will continue to be commented on and refined over time. Given that MBPs offered within secular settings in most countries currently have limited oversight or accreditation processes, we hope these guidelines will provide support and clarity to the teachers of all established and emerging MBPs, and their trainers and supervisors.

Background The Mindfulness-Based Interventions: Teaching Assessment Criteria (MBI:TAC) is a widely used tool for assessing fidelity in mindfulness-based program (MBP) research and training. It also supports MBP teacher reflective and skill development. MBI:TAC assessors review MBP teaching and rate the teaching on 6 domains. The MBI:TAC yields individual domain and overall scores, using 6 levels of competence. Although the MBI:TAC is widely used in MBP research and training, research is at an early stage. Objective We developed and tested a method of training MBI:TAC assessors to use the tool reliably and examined interrater reliability of the tool. Methods A total of 31 international senior MBP teachers were recruited to join an online training to build their skills in using the MBI:TAC. The training systematically and iteratively built familiarity and skills in assessing the 6 MBI:TAC domains. Qualitative and quantitative data on trainee’s experience of the training were gathered. Interrater reliability in using the tool was tested each week of the training. At the end of the training, interrater reliability was tested by asking trainees to individually assess videos that they had not previously seen. Their ratings were compared to benchmark assessments, which had been established via consensus agreement between 4 expert users of the MBI:TAC. Results The training was well received and appreciated, with some challenges experienced in applying the assessment methodology. Participants’ ratings became progressively more in line with one another and the benchmark ratings during the training. At the end, interrater reliability was high (ranging from 0.67 to 1.0). Conclusion It is possible for senior MBP trainers, coming from different regions in the world, to align toward common understandings of the elements of MBP teaching competence and program integrity. An assessor training methodology was tested, and the learning from this project has led to refinements for future delivery.

The Mindfulness-Based Interventions: Teaching Assessment Criteria (MBI:TAC) was originally developed as a tool to assess the teaching competence of mindfulness-based program (MBP) teachers. The tool was made freely available and has since been used by mindfulness-based teacher training organisations internationally. During this time the MBI:TAC has evolved in its usage, from an assessment tool to one which informally supports how MBP teachers are trained. In this article, we first examine the rationale for implementing the MBI:TAC in MBP teacher training; second, we offer practical guidance on ways of integrating the tool into teacher training pathways with awareness of its potential and possible pitfalls; and third, we offer guidance on using the tool as a framework for giving effective feedback to trainees on their teaching practice. Implementing the MBI:TAC in teacher training may support the quality and integrity of MBP teacher training, and thus ensure high quality MBP teachers graduating. In turn this may help avoid the ‘implementation cliff’ – that is, the quality of an intervention delivery is delivered in optimal conditions when it is being researched, and drops in quality when delivered in sub-optimal, ‘real world’ conditions.
