Swansea head teacher on the 'challenge' of the job
There was a 66% drop in applicants for secondary school leadership posts over two years, new figures show.
The Education Workforce Council said the situation was not a "crisis" but said fewer applicants for secondary and primary head teacher posts was a "challenge".
It said the need to get a mandatory qualification to qualify as a head teacher was "a limiting factor" in expanding the pool.
A new National Academy for Education Leadership is being established to develop the skills of school leaders.
Ruth Davies has been head teacher of Waunarlwydd Primary School in Swansea for the past 13 years.
She said the job had changed and the remit had grown wider but children were now more involved in their education.
