After the domains are listed and the knowledge and skill statements are written into outline form, the elements of the JTA ouline need to be weighted. This ensures that the most important domains are given the correct amount of attention on the exam. Weighting is addressed in terms of importance, criticality, and frequency.

Regarding importance, the best way to rate the importance of a domain is to ask yourself this question, "How significant is this domain to the everyday activities of a qualified person doing this job?"

The next part is to rate the criticality of the domain. In other words, if the tasks in a particular domain are not performed correctly, how much harm can be caused to the stakeholders?

What is harm?


Harm can be physical, mental, financial, emotional, legal, etc.


The final part of weighting is frequency. This means in a roughly 1-year period in a qualified person's job life, how often will they be performing this particular domain?

Rate the Importance, Criticality and Frequency using the table below:




0 = Not Important

0 = No Harm

0 = Never

1 = Of Little Importance

1 = Minimal Harm

1 = Rarely

2 = Moderately Important

2 = Moderate Harm

2 = Sometimes

3 = Very Important

3 = Substantial Harm

3 = Often

4 = Extremely Important

4 = Extreme Harm

4 = Repeatedly




Naturally, areas of the outline that are more important, more critical and performed more frequently, require more test questions on the examination than areas that are of little importance, cause minimal harm if done incorrectly and are rarely seen.
