When organizations are thinking about staffing an arts position on a tight budget, they often cast the position as an "entry-level" position because of the parttime nature, low salary, lack of job security and no-benefits nature of the position. Sometimes this judgement is made without consideration of the demands of the job description. In some cases the position IS a great fit for a newly graduated student. In other cases, although few hours are demanded, the skill set needed is varied and requires on-the-job experience for success.
If an organization needs experienced grantwriting, financial management/budgeting, and arts marketing savey, they are unlikely to find that in an entry level staff person. It takes a few years of working in an effective team setting to learn these highly specialized skills. A great fit for such an organization may be an arts worker at the other end of the spectrum, easing into retirement or exiting full time arts administration in order to work on their own artistic or entrepreneurial projects.
