What parenting programmes are available and how long are they?

There are separate parenting programmes for babies aged 0 to 1, toddlers aged 1-3, pre-schoolers aged 3-6 and school-age children aged 6-12. Programmes vary in length from 8 to 20 weeks. Visit Incredible Years.

What is the general format of sessions?

The programme is designed to be responsive to a variety of learning styles and capabilities. The programme operates a collaborative model based on Social Learning Theory whereby parents are encouraged to share their experiences in a non-judgemental environment, view video examples and have opportunities to practice new parenting skills in the session and at home. Weekly sessions involve two group leaders and are generally 2 to 2 ½ hours in length. Ideally, groups include between 10 and 15 parents.

Is there any research to support the use of this programme?

International Research

There is considerable international research evidence supporting the effectiveness of this programme with a diverse range of populations.  A detailed list of research articles can be found on the Incredible Years® website -

Internationally, the Incredible Years® programme has been formally recognised –

  • selected by the U.S. Office of Juvenile Justice and Delinquency Prevention as an "exemplary" best practice program and as a "Blueprints" program.
  • selected as a "Model" program by the Centre for Substance Abuse Prevention (CSAP). As such, the series has been subject to numerous randomized control evaluations, evidenced excellent effectiveness, and attained high overall ratings.
  • recommended by the American Psychological Division 12 Task force as a well-established treatment for children with conduct problems.

New Zealand Research

An increasing body of evidence from New Zealand-based research, so far fully supports the international research and the programme’s applicability to the New Zealand cultural context.  This has included an evaluation of a marae-based programme, utilising Māori-specific outcome measures, supported the use of Incredible Years® as an effective intervention with Māori families (Altena & Herewini 2008).  

A joint interagency evaluation has also suggested equally high positive outcomes for families/whanau and equally high satisfaction ratings (Ministry of Education, Ministry of Health, & The Werry Centre 2012).

What are the minimum group leader requirements for delivering a parent programme?

Group Leaders should ideally have a background in Nursing, Social Work, Psychology, Psychiatry, Family therapy, Counselling or Teaching, and a sound knowledge of child development.  A three-day basic training is offered throughout New Zealand providing facilitators with an introduction to the programme and the skills required to deliver the programme.

How can I access training in The Incredible Years® Parent Programme?

Three day basic training workshops are provided by Werry Workforce Whāraurau throughout the year. Registration is via the website. Check out Workshop overview for more information on workshops and register here

What does the training involve and how much does it cost?

The Incredible Years Basic Training Workshop is provided by an Accredited Mentor and runs over 3 days. This training includes:

  • a summary of the theory, research and background to the programme
  • an overview of the programme content
  • an opportunity to become familiar with the session format
  • practical and experiential learning
  • opportunities to practice group facilitation skills

Facilitators must attend all 3 days to obtain their training certificate. The training is free of charge to participants.

Visit Workshop Overview for more information.

What follow up support is provided to Facilitators after completing the 3 day basic training workshop?

Werry Workforce Whāraurau offers ongoing support and professional development opportunities for trained group leaders to ensure programme fidelity and best outcomes for families. Explore the Workshop Overview for a description of all workshops and visit ‘Programme Fidelity’ for how to achieve Accreditation as a group leader.

Māori and Pacific group leaders are offered enhanced support through targetted funding. This includes Māori hui and Pacific fono, and culture-specific workshops enabling group leaders to share experiences, develop skills, and consider ways in which Incredible Years® can be woven into Māori and Pacific world views and customs.

What is the value of becoming an Accredited Group Leader?

Accreditation is achieved when group leaders demonstrate consistent adherence to programme fidelity. Programme fidelity ensures that families achieve their parenting goals, so group leaders who achieve Accreditation can be confident that they are providing an effective evidence-based programme which maximises positive outcomes for parents. Support for group leaders who are progressing towards Accreditation ensures that it is both a challenging and rewarding experience which is invaluable for professional skill development. Social service agency employers can be confident that group leaders are operating within a “best practice model” for families. The core collaborative and strengths-based approaches of the Incredible Years Parent Programme apply equally to all family support interventions.

What does Accreditation involve?

Accreditation as a group leader involves submitting a filmed group session for review, completing paperwork including an application form and parent evaluations from two complete programmes. Review of group leaders work is provided by a Mentor who gives feedback and assesses whether the programme is being run with fidelity.  A complete list of the requirements for attaining Accreditation as a group leader is available from the following link -

How can I apply for Accreditation?

Consultation Days are offered throughout the year for Group Leaders who have completed training and are delivering groups.  Werry Workforce Whāraurau also support Peer Coaches to deliver Programme Fidelity Workshops. For more information visit ‘Workshop Overview’ or contact Lisa Glynn, Incredible Years Project Manager at [email protected].

Group Leaders can also apply for Accreditation directly to Incredible Years in Seattle – see


What further opportunities are there for Group Leader progression?

Werry Workforce Whāraurau is committed to supporting the on-going development of group leaders and to the sustainability of The Incredible Years workforce in New Zealand. Regular Consultation Days are offered each year for all group leaders, including accredited leaders.

Once a group leader has achieved accreditation, experienced group leaders may be nominated by a Mentor to progress towards Accreditation as a Peer Coach. Not all group leaders are eligible to progress in this manner. More information about Peer Coaching is available here. Peer Coaches may be eligible to work towards Accreditation as a Mentor, if nominated and seen to be appropriately experienced and skilled.

If I attend an Incredible Years group, what will be the benefits for me?

You will have an opportunity to share your experiences with other parents facing similar challenges with their children. You will explore new ideas for parenting your children, and you will have an opportunity to practice new parenting ideas in a safe and non-judgemental environment. Parents who complete the programme generally experience improved relationships with their children, less stress, improved mental health and fewer problem behaviours in their children.

What have other parents said about the programme?

“Praise works rather than negative attention.”

“I learnt to control my temper.”

“I reckon my anger’s gone … I kicked it to the curb.”

“My girl’s smiling all the time now and so am I.”

“My Mum’s even copying me now in the way she talks to her moko.”

Can I bring whānau or a support person with me to the group?

The programme encourages parents to bring along a support person or whānau member to weekly sessions. Please speak with your group leaders about guidelines.

Do children attend the groups?

The focus of the parent programme is to provide you with an opportunity to share with other parents and learn new skills in a safe and non-judgemental environment. Generally, parents make arrangements for their children to be cared for elsewhere while they attend so that they can fully participate in the learning of new skills. However many groups do include children (such as marae-based groups), so please discuss your needs with your group leaders before the beginning of the programme.

What age range does the Incredible Years® parent series cover?

The Incredible Years® series of parent programmes cover the following age ranges –

Parent and Baby Programme 0 - 1 year
