Purpose of the Questionnaire (Scale)

The primary purpose of the CGT is to assess basic cognitive and practical abilities, aiming to support educational and professional guidance. The test is intended for individuals who wish to identify their potential in fields such as sciences, engineering, economics, and technological sectors. It measures linguistic, numerical, mechanical, and spatial abilities.

Questionnaire (Scale) Analysis

The CGT was developed by Konstantinos Papadopoulos, psychologist and expert in psychometric evaluation. It consists of four subscales:
The first concerns Linguistic Abilities and evaluates reading comprehension.
The second relates to Numerical Abilities, including mathematical skills and logical thinking.
The third subscale measures Mechanical Abilities, examining the understanding of mechanical systems.
The fourth focuses on Spatial Abilities, i.e., the ability to perceive and manage shapes in space.
The test consists of 60 multiple-choice questions and lasts approximately 60 minutes.

Scoring of Questions

Each subscale is scored based on the accuracy of responses. The overall scores form a detailed profile of abilities, which is then compared with statistical data for interpretation. For example, a high score in spatial ability may indicate suitability for fields such as architecture or engineering.

Statistical Analysis

The maximum and minimum values of each subscale depend on the number of questions. Statistical results allow for an objective assessment of the examinee’s abilities and strengthen the validity of the interpretation. Examples of correlations show that high scores in specific subscales are associated with certain career paths.

Validity of the Questionnaire (Scale)

The CGT demonstrates high validity. Research has confirmed the correlation of its results with other well-established cognitive tests. Recent studies from the past five years, both internationally and in Greece, have reinforced the reputation of the test as a valid assessment tool. In the Greek literature, a representative work is Papadopoulos’ Career Gate Tests: A Tool for Assessing Cognitive Abilities.

Reliability of the Questionnaire (Scale)

The test is characterized by high reliability. Cronbach’s alpha values exceed 0.85 for all subscales, demonstrating the stability and consistency of its results.
