FAQ Connector Ability - PiCompany

1. After taking the practice test on your website, a candidate took

the actual Connector Ability test. The score on the practice test

differs a lot from the score on the Connector Abilit y. How is that

possible? How to handle this?

It can happen that someone‟s score on the practice test differs from the score on the actual

Connector Ability test. PI Company offers the Connector Ability as the actual selection test

because this test has been developed especially for this purpose; this test meets the highest

criteria with respect to reliability and validity.

In contrast to the Connector Ability, the practice test is a test that consists of a fixed number of

questions that can be practiced as often as one wishes.

We advise our customers to stress to candidates that the primary purpose of the practice test

is indeed to practice with the type of questions that will also be offered in the actual test. The

practice test is meant for preparation and gives only an indication of the level someone can

achieve.

The difference between the outcomes on both tests, can depend on one of the following

aspects:

Type of test: the Connector Ability test is more reliable and more valid than the

practice test.

Norm group: the highest available norm group for the practice test is a Bachelor‟s

norm group (BA). Comparing test outcomes needs to be based on the same

educational reference group. People with a Masters educational level (MA)

achieve on average a higher score (on both tests) than people with a Bachelors

educational level (BA). Therefore, when a person‟s scores (on the Connector

Ability) are compared to the scores of a MA norm group, this person will have a

lower outcome than when scores (on the practice test) are compared to a BA

norm.

Effect of practicing: one can take the practice test as often as one likes; the

questions stay the same. By practicing, the score on the practice test can keep

increasing.

Conditions under which the tests are taken can differ:

Often the practice test will be taken at home, the Connector Ability will more often

be taken at the office.

Some people achieve less well when they feel themselves under pressure; when

they take the actual test, whether or not at the organisation‟s office. Someone

can then score below his/her real intelligence level. The other way around, some

people achieve better results under pressure, when taking the actual test.

In addition, there can be more reasons why someone sometimes does not

achieve in an optimal way. For example, because of illness but also when

someone is interrupted or disturbed while taking the test.

10. What is the difference between G -factor and IQ?

There is no real difference. IQ is just a specific measurement scale that refers to the total

world population (mean 100, range 15). In general, organisations that wish to use intelligence

tests, like Connector Ability, want to compare a person to a more specific norm group, most of

the time a group of people with a specific educational level (for example Masters). Then it is

not necessary to estimate the IQ-score in addition to the t-score, the score used to compare

the score of a person with the norm group scores.

11. Does the speed of answering have an effect on the Connector

Ability score?

The speed has no effect on the test‟s score, because speed is not included in the

calculation of the score. A candidate has 1.5 minutes to answer a question. Answering

earlier does not cause a higher score and also doesn‟t provide more or less questions in

the test. However, a right or a wrong answer does. An adaptive questionnaire means that

a right answer is followed by a more difficult question, whereas after a wrong answer a

more easy question is presented. The test continues until there is a reliable calculation of

how difficult a question must be should the candidate only just be able to answer it

correctly. So with an adaptive questionnaire the speed of answering doesn‟t matter,

because more difficult questions can be presented earlier, namely when the answer to

the question is correct.

A „classic‟ intelligence test is usually a „speed and power‟ test. That means that the

questions at the end are more difficult than at the beginning, and that it is important to

work correctly and fast, so that there is enough time to get to the more difficult questions

and to, hopefully, answer these correctly.
