The legislature finds the interests of the state and its citizens are best served by a strong education system. Paramount to that system's success is the attraction and retention of qualified instructors. In order to attract and retain instructors, those who are subject to uncertainties of employment must be provided assurance that their economic needs are addressed. Contingent assurances of future employment are often speculative and do not rise to the level of other forms of assurance. As such, the factors presented in RCW
50.44.053 must be used to determine if reasonable assurance of employment exists.
