Whilst Avigail is well known for her studio and performing work, she has also spent a large part of her career as an educator and passionate advocate for the training of Music Theatre performers.

From 1989 to 2010 Avigail was associated with the National Institute of Dramatic Art (NIDA) beginning her time there as a singing tutor. In 1993 she took over the full time position of Head of Music, a position she retained until 1997.

Avigail introduced many new and innovative courses into the school but most importantly was a key element in raising the profile of music theatre there. In the five years from 1993 to 1997, whilst Avigail was in the position of Head of Music, NIDA third year students presented very successful productions of Guys & Dolls (Tony Knight director, Nancye Hayes choreographer and Avigail Herman music director) and The Pajama Game (Tony Knight director, John O'Connell choreographer, Avigail Herman music director). As well, there were productions of musical plays such as Oh What a Lovely War (John Clark director, Avigail Herman music director) and Ghetto (Ros Horin director, Avigail Herman music director).

At this time, the NIDA Company (professional wing of NIDA) undertook the workshopping of three new Australian Musicals, Villain of Flowers and Nathaniel Storm by Anthony Crowley and Wedding Song by Stephen Rae and Hillary Bell. Avigail was intrinsically involved with the development of these pieces.

In 1999, after having a break from NIDA Avigail along with Keith Bain set up and developed NIDA’s very successful one year Music Theatre course ‘Singer Dancer Actor’ which in 2009 became a Diploma of Music Theatre.

This was a course to train young people in the art of becoming a ‘triple threat’, with a holistic vision and professional philosophy. The course was a resounding success with graduates making an impact on the profession both in Australia and overseas. Avigail continued to head the course after Keith retired seeing through the last graduating year of 2010.

Avigail’s particular teaching expertise is in the area of the integration of music and text or the art of story telling through song. As such, she was invited as a guest lecturer for a semester at Carnegie Mellon University in Pittsburgh USA.

Her Master classes are in demand and she has taken workshops for the Adelaide Cabaret Festival, Australian Theatre for Young People (ATYP), Melbourne Cabaret Festival, Noosa Long Weekend Festival, NIDA Summer School, Queensland Performing Arts Trust (QPAT), schools, choirs and institutions across the country and the Talent Development Unit for the NSW Department of Education for whom she consults.

Her other teaching credits include: setting up the Music Department for David Atkin's one time performing arts school "Dynamite"; a syllabus consultant for TAFE's Music Theatre Certificate; teaching score reading to the Opera House Stage Managers and working with the third year NIDA students on studio work (i.e. voice overs etc).

Such is the quality and diversity of Avigail's teaching that she is in constant and high demand from institutions and organisations both nationally and internationally.
