3. Cutoff Scores: In a certain City of Townsville, people love their dogs. Dog groomers are very popular and are found throughout the city. In order to become a dog groomer, one must obtain a coveted "dog groomer license" which is granted by the City. In order to be awarded such license, a person must pass a city administered "dog groomer license" test. The City has hired you to explain to them how to set a cut score so they can decide for themselves where to where set it for their test. Their goals are to 1. make sure someone who is awarded a license can in fact groom dogs, and 2. to make sure too many people aren't awarded licenses reducing their value and prestige. Records indicate that approximately 250 people take the licensing test each year and of those, roughly 75 licenses are awarded. Assume that the distribution of scores on the test is approximately normal. In your recommendation to the City provide the following information A. The steps you would take to determine a cr B. The steps you would take to determine a norm referenced cut score C. The advantages and disadvantages of each method D. How the cut score impacts their two goals above (you can talk about false cut score positive and false negative errors here) Since no detail is provided with respect to individual test scores, you don't need to be detailed with what particular score a cut-off would be set at. It is more important for the City to understand conceptually what each method is, the steps needed to do each one, and what effects raising or lowering the cut score will produce.

Explanation / Answer

A.STEP THAT WOULD TAKE FOR CRITERION REFERENCED CUT SCORE:Criter refrenced test are designed to measure persformance on the basis of predetermined criteria.Here also such kind criteria is fixed to provide licence to dog grommer liketo judge person should really a grommer of dog through assessment of questions.there is criteria fixed that only 75 person should given license out of 275. So on the basis of cut off score of performance, top 75 dog groomer should awarded licences.major step of criterion reference test is

1.identifying the structure and components of skill like the person who do grommer does really capablity to groom dog or not.

2.Developing task for each components, like in which prrocess would like to take test theoretical or impirical .

3.develpping test for group of components that represents all other.

4.mapping the developo process on sample.

5.setting the criterion characterising the optimal funtioning skill.

B. Step to determine norm reference criterion test:here person should learn specific skill, achieve specific learning , achievement of pre determined norm then it would called norm refrenced criterion.

Major step to determine of cutoff:

1st step: Designed test, test should designed where 30 to 70 people can give the answer.

Step 2:interpreting performance, so now interpret what they have done in test.

Step 3:constructing norm, like convert raw to derived score through percentile.

Advantage:

1.in criterion refrenced test , performer are only test on their knowledge of specifc goal.

2.In norm criterion reference test helps to understand primarily how a learner perfrom better as compare other.

Disadvantage:

1 in criterion reference test, creating test that are both valid and realiable taking more time and expensive.

2.when compare the norm refrenced test with other test , then can find high degree of error on it.
