Recommended Experience Levels

The Writers’ Federation of Nova Scotia (WFNS) recommends that each workshop’s participants share a level or range of writing / publication experience. This is to ensure each participant gets value from the workshop⁠ and is presented with information, strategies, and skills that suit their current writing priorities.

To this end, the “Recommended experience level” section of each workshop description refers to the following definitions developed by WFNS:

  • New writers: those who have been writing creatively for less than two years and/or have not yet been published in any form.
  • Emerging writers: those who have been writing creatively for less than five years and/or have some short publications (poems, stories, or essays) in literary magazines, journals, or anthologies.
  • Established writers/authors: those with numerous publications in magazines, journals, or anthologies and/or a full-length book publication.
  • Professional authors: those with two or more full-length book publications.

For “intensive” and “masterclass” workshops, which provide more opportunities for peer-to-peer (that is, participant-to-participant) feedback, the recommended experience level should be followed.

For all other workshops, the recommended experience level is just that—a recommendation—and we encourage potential participants to follow their own judgment when registering.

If you’re uncertain of your experience level with regard to any particular workshop, please feel free to contact us at communications@writers.ns.ca
