In a typical school year, every school district will have vacancies created, although the nature and scope of those vacancies will vary depending upon individual circumstances.
Vacancies occur as a result of superannuations, resignations and death, among other reasons.
Teacher demand may be defined as the number of teachers needed to fill the available vacancies. While aggregate demand refers to the actual number of vacancies, relative demand refers to the number of vacancies in relation to selected demographic or geographic indicators. Error bar charts are used to show the estimated dispersion of the population from which the sample was drawn. They are used here to show 95 percent confidence intervals for the mean for each of the demand indicators. Demand conditions School districts were asked to indicate the capacities, subject areas and skills in which they were experiencing the greatest demand.
