In this article we will discuss about the meaning and measurement of aptitude.
Meaning of Aptitude:
An aptitude is not the same thing as ability or interest, as it is more specific, measuring only certain aspects of functioning within a limited range. A person with a verbal ability cannot have aptitude for all the different tasks or vocations connected with verbal ability. The delimitation of the area is a result of the influence of the environment and personal cultivation for a period of time. Aptitude is only in part inborn or native.
The most appropriate explanation of aptitude is given by Bingham, which is included in Warren’s Dictionary of psychology. He defines aptitude as- “A condition or set of characteristics regarded as symptomatic of an individual’s ability to acquire with training some (usually specified) knowledge, skill or set of responses, such as ability to speak a language, to produce music …”

Bingham further states that aptitude is a measure of probabilities of success of an individual with training is certain type of situations such as playing violin. So aptitude is something more than the ability. It is ability plus suitability of performance. A person may be a good scholar, because he possesses high verbal ability, but not necessarily a good teacher.
Teaching aptitude depends upon not only high scholastic ability, high interest in teaching, but also some personality traits which are wanted in a teacher. Every person with high measure of scientific ability cannot prove to be a good doctor unless he possesses some further traits like perseverance, sociability, love of humanity, dexterity of fingers to perform an operation etc.
Aptitude, in reality predicts what a person is fit to be:
Achievement looks to the past, indicating what has been done.
ADVERTISEMENTS:
Ability concerns the present, indicating the powers now.
Aptitude looks to the future, predicting what he may become.
Aptitude is a result of both heredity and environment. The primary mental ability which is a major factor herein is hereditary. The readiness to acquire knowledge or skill, and the satisfaction in the activity is cultivated on the effect on environment.
Some of the chief characteristics of an aptitude are the following. It is of a specific nature, as it is not common to all the situations where a particular ability is used. As it cannot be further analysed into simpler abilities, it is unitary. It remains, more or less constant. It implies facility of learning or readiness to acquire a particular job.
How to Measure Aptitude:
Aptitude can be measured through a multiple evidence which includes past academic achievement of the pupil, occupational status of the parents, the observation of the teacher, the hobbies selected by the pupil, the interview, self-estimate by the pupil, a situation test and a standardised aptitude test. The most important of the above means in the aptitude test.
