Aviation Selection Test Battery (ASTB) - Virginia Tech

1 Aviation Selection Test Battery (ASTB) The Aviation Selection Test Battery (ASTB) is used by the Navy, Marine Corps, and Coast Guard as one criterion used in making Selection determinations for officer Aviation program applicants. The most recent complete revision of the ASTB was completed by the Naval Operational Medicine Institute (NOMI) in cooperation with the Educational Testing Services (ETS) in Princeton, New Jersey in 1992. In 2004, three new parallel forms of this ASTB version were released by NOMI, and Forms 1 and 2, which had been in circulation from 1992 to 2004, were suspended.

2 The ASTB is used by the Navy Personnel Command (NPC) and Commandant Marine Corps to select candidates for the Navy and Marine Corps pilot and flight officer programs. Portions of the test are also used by the Navy for Selection into Officer Candidate School (OCS). The Coast Guard currently uses the ASTB to select pilot candidates for training, and uses a subcomponent score from the ASTB for its non Aviation officer commissioning program. ASTB Administration Procedures and Policies The ASTB is administered at Navy Recruiting Districts (NRDs), NROTC units, Marine Corps Officer Selection Offices (OSOs), and at numerous other permanent custody sites.

3 The test is administered in a paper format, but at many sites it can be administered on a computer through a web based system called There are three versions of the test Form 3, Form 4, and Form 5. Each version of the test contains different questions, but all three versions have the same format, subtests, and number of questions. The complete test Battery contains 6 subtests and requires approximately 2 hours to administer. Retest Policy: Examinees that would like to improve their scores on the ASTB must wait until the 31st day following their initial attempts before taking different versions of the test.

4 For example, an individual that takes Form 3 during their first administration must take Form 4 or Form 5 during their second testing session. A third and final attempt at Form 3, 4, or 5 is authorized on the 91st day following the first retest. These test interval requirements cannot be waived, so it is important that examinees are aware of the forms taken during previous administrations and the amount of time that has passed between administrations. Please talk to your recruiter or call 850 452 2257, and choose Option 3 followed by Option 5 if you are unsure of your test date or form number.

5 3 Test Lifetime Limit: A major change regarding the administration of the ASTB was the establishment of a 3 test lifetime limit in July 2004. An examinee may only take each version of the test (Form 3, Form 4, and Form 5) once, which means that an individual will only be allowed to take the ASTB 3 times during his or her lifetime. Examinees must take a different form during each retest, but the forms can be taken in any order. This limit only applies to Forms 3, 4, and 5. Therefore, if individuals took a previous version of the test (Forms 1 and 2, which are longer in use), it is not counted in this limit.

6 Illegal Testing: An examinee that retests too early or retests using a form that he or she has already taken will generate an illegal test. An illegal test means that the individual will not receive valid scores for the testing administration. On the other hand, the illegal test will still be counted against the individual s lifetime Scoring and Examinee Distributions The current version of the ASTB was constructed and validated to predict both performance and attrition through the primary phases of Aviation training for Student Naval Aviators (SNAs) and Student Naval Flight Officers (SNFOs).

7 The entire test Battery consists of 6 subtests: ASTB Subtest Length Time Limit Math Skills Test (MST) 30 items 25 min Reading Skills Test (RST) 27 items 25 min Mechanical Comprehension Test (MCT) 30 items 15 min Spatial Apperception Test (SAT) 25 items 10 min Aviation and Nautical Information Test (ANIT) 30 items 15 min Aviation Supplemental Test (AST) 34 items 25 min During the test administration, examinees have the option of taking the entire test Battery or the OAR portion of the test, which consists of the Math Skills Test, Reading Comprehension Test, and Mechanical Comprehension Test.

8 Examinees that take only the OAR portion will receive only one score, the Officer Aptititude Rating (OAR), which is used to predict academic performance in Navy Officer Candidate School (OCS). OAR scores range from 20 to 80, and are scaled as t scores. Distribution of OAR Scores Fiscal Year 2004 0 50 100 150 200 250 300 350 400 450 20 25 30 35 40 45 50 55 60 65 70 75 80 OAR Score Number of Examinees N=7789 OARThe chart shows the distribution of OAR scores for all examinees taking the ASTB in one year. The green band shows that most examinees obtain scores between 40 and 60, while very few individuals obtain scores at the upper and lower extremes of the score range.

9 Test Merges: Applicants who have taken only the OAR portion of the ASTB (MST, RCT, & MCT) may take the remaining portions (SAT, ANIT, & AST) to obtain a complete set of scores. Examinees must take the remaining portions within 90 days of the initial test, and the test date of the SAT, ANIT, & AST become the official test date for the complete exam. The test merge will count as only one attempt against the examinee s 3 test lifetime limit. Examinees that take the entire test Battery receive 4 scores that are derived from combinations of the subtests.

10 The following three scores are relevant to the Selection of Aviation candidates: The Academic Qualifications Rating (AQR) is predictive of academic performance in Aviation preflight instruction (API) and primary phase ground school. The Pilot Flight Aptitude Rating (PFAR) is predictive of primary flight performance for Student Naval Aviators (SNAs). The Flight Officer Flight Aptitude Rating (FOFAR) is predictive of primary flight performance for Student Naval Flight Officers (SNFOs). Along with these three scores, individuals that take the entire test Battery also receive an Officer Aptitude Rating.
