Beta Exams: Why Are They Longer?
By Harold Green on Aug 29, 2008
Question: Why Is The Test So Long? (a.k.a. Why Does The Test Have So Many Questions?)
Answer: During exam development we write a large pool of questions for several reasons. The quick answer?
- So we can create multiple versions of the exam, and...
- So we have a pool of a sufficient size that allows us to remove poorer questions, leaving only the "best" questions.
The beta exam is critical, allowing us to evaluate each question for its difficulty and ability to measure the candidate’s knowledge. In addition to the data collected and analyzed for each question, there is also important data obtained from the questions' performance relative to each other as well as to the exam as a whole.
So yeah - it's important that we include every question in the beta exam pool.
Although it takes longer to answer all of these questions, there is a tremendous benefit:
Firstly, you are direcly helping ensure that all versions of the exam are fair; i.e. every future exam has the same difficulty and comprehension regardless of version.
Secondly, you are directly helping determine which questions are selected for the final versions, and which ones... "kinda need to go."
Oh. And you are scored only on those questions we choose to keep in the final exam versions (more good news).
So get a good stretch, get comfortable at the testing station, and help us in making these certification exams as fair and straight-forward as possible.
