General Science ASVAB

Importance of General Science ASVAB Test

Every year, thousands of school students as well military aspirants take up the ASVAB test as a career exploration and self assessment tool, as well as a part of the military enlisting process. The test is a battery of varied subtests that evaluate and measure the candidates' abilities, skills, and aptitudes in various core areas, including the General Science. Read on to find out why and how the General Science ASVAB test is important in ASVAB.

The Importance of ASVAB Test

Though the beginning of military enlisting tests can be traced back to the World War I times, it was in 1968, the Armed Services Vocational Aptitude Battery (ASVAB) exam was first introduced. By 1976, all the US armed forces accepted the ASVAB exam as part of their enlistment processes. Today, though the test is used both as a career exploration tool and an aid to military enlisting and classification process, the test pattern and content are the same for all purposes. The different core areas covered in the test battery, including General Science, ensure that the test does a comprehensive evaluation of the candidates' skills, aptitudes, and knowledge in all the important areas, and accordingly predict their chances of success in various career options including that of military services.

ASVAB Test Content and Subtests

In general, the ASVAB exam is administered either as a paper and pencil-based version (P&P-ASVAB) or as a computerized, adaptive version (CAT-ASVAB). However, the test content is the same across both the versions, with multiple subtests that evaluate the candidates' skills and knowledge in the following core areas:

  • Mathematical
  • General and Technical Science
  • Spatial
  • Verbal

The number of subtests, however, varies in both the versions of the ASVAB exam - ten subtests as follows are administered in the CAT-ASVAB, while in the P&P-ASVAB, the AI and SI subtests are clubbed into one single subtest Auto and Shop Information (AS). Yet, the General Science ASVAB test is common across both the versions of ASVAB.

  • Arithmetic Reasoning (AR)
  • Assembling Objects (AO)
  • Auto Information (AI)
  • Electronic Information (EI)
  • General Science (GS)
  • Math Knowledge (MK)
  • Mechanical Comprehension (MC)
  • Paragraph Comprehension (PC)
  • Shop Information (SI)
  • Word Knowledge (WK)

It should also be noted that the test content and subtest remain the same across all the branches of US military services.

The General Science ASVAB Test

There are multiple subtests included from various core areas to ensure that the candidates are tested in all the relevant areas that provide clues to their eligibility to military and non-military career options. The General Science ASVAB test, for example, tests and evaluates the candidates' abilities and skills in the physical and biological areas relevant to various career options.

As like all the other ASVAB subtests, the General Science ASVAB subtest also consists of multiple choice questions. For sample questions, refer to the official ASVAB website:
The number of questions in the General Science ASVAB subtest differs according to the version of the test administered. While the CAT-ASVAB has 16 questions, the P&P-ASVAB version has 25 questions. The time limit given to the General Science ASVAB subtest in each of these versions is also different - 8 minutes in the CAT-ASVAB and 11 minutes in the P&P-ASVAB respectively. However, as all other subtests in the CAT-ASVAB, the General Science ASVAB subtest also could be finished off well ahead of the time limit, as per individual candidate's pace.

You can find the time limits for individual subtests and the corresponding number of questions in each at:
Also, as the ASVAB exam standard scores are used both for classifying candidates into the best suitable job roles within the appropriate armed force branches, the scores of all subtests, including that of General Science ASVAB subtest are critically important. For example, for careers in the Science and Technical domains, the General Science ASVAB subtest scores are always considered. Accordingly, the General Science ASVAB subtest should be given its due importance while preparing for the ASVAB exam. Based on the candidate's aspirations, interest areas, skills, and the wing of service they are interested in, they need to set their General Science target scores, though.
