2. Objectives Review History, Purpose, Content, and Scoring of the ASTB in Naval Aviation
Where we have been
Provide an Update on ASTB Administration Rates, Performance Trends, and Demographic Breakouts (Incl. Predictive Relationships w/Training Criteria & Student Attrition)
Where we are now
Present Short-Run and Long-Term ASTB Revision, Upgrade, Validation, and Administration Efforts
Where we are going
3. Background & Overview Primary tool used to select SNAs and SNFOs flight officers for the USN, USMC, & USCG
Different sections of the battery are also used to select OCS candidates and Intel officers
ASTB was first implemented in 1942, with revisions in 1953, 1971, and 1992
1992 ASTB revision was validated separately for SNAs and SNFOs; also developed to be bias-free for gender/ethnicity (with ETS)
4. ASTB Content & Scoring The 1992 ASTB primarily consists of four subtests*
Math - Verbal Test (MVT)
Mechanical Comprehension Test (MCT)
Spatial Apperception Test (SAT)
Aviation and Nautical Test (ANI)
*Discontinued Biographical Inventory & Aviation Interest
Weighted subtest score combinations yield stanine (1–9):
Academic Qualification Rating (AQR) - Predictor of performance in academic portions of API and ground school (also predicts attrition)
Pilot Flight Aptitude Rating (PFAR) & Flight Officer Aptitude Rating (FOFAR) - Predictors of flight grades in primary flight training (also predicts attrition)
5. ASTB Administration 150 permanent custody locations: OSOs, NRDs, NROTCs, USNA, & select air stations
All completed ASTBs are returned to NOMI for scoring, reporting, & database inclusion
NOMI procures, distributes, scores, & controls of ALL ASTB test materials.
On-line delivery system for the ASTB (APEX) was developed and is in use at over 20 sites
Had successful overseas and shipboard administrations
Transitioning to primarily on-line administration at all permanent custody locations in FY05
6. ASTB Administration Rates AVG 10,000 ASTBs (full or partial) per year
Over 120,000 1992 versions taken (June 04)
75,000 Full ASTBs (Total Aviation Examinees)
19,000 ASTB Retests
26,000 OAR Exams
5% of all ASTBs currently taken on APEX
7. Historical ASTB Pass Rates by Service and Program
8. Predictive Relationships with Training Outcomes and Attrition Validity data presented for FY98-FY04
The validity coefficient (higher is better)
Test Components:
AQR: Predictor of NASC NSS
SNA: USN .46 USMC .39 SNFO: USN .46 USMC .34
“Excellent”
PFAR & FOFAR: Predictors of Primary NSS
SNA: USN .32 USMC .21 SNFO: USN .27 USMC .18
“Good”
9. Predictive Relationships Among ASTB Components and SNA AttritionFY 98-FY 04 JUN
10. *: N<50*: N<50
11. Predictive Relationships Among ASTB Components and SNFO AttritionFY 98-FY 04 JUN
12. *: N<50*: N<50
13. Reasons for Attrition (from CNATRA Database)FY 95-FY 04 May
14. Semi-annual CNATRA Attrition Survey Received responses from 73% of attriters (n=120); 49% of those surveyed DORed
Top three reason for DORs:
Loss of (or never had) interest in flying (27%)
Apprehension of flying or thinking of it (26%)
Nervousness/Anxiety with flight program (22%)
15. Parallel Forms Development NAMI began item development for replacements of 4 current subtests in JUN 02; 2500 items developed by 30 item-writers over 13 mo
Reduced these to 4 types (2 booklets each)
200 Math
172 Aviation Info
131 Reading Comp
152 Mech Comp
NETC provided$130K for travel,printing, & labor
16. Parallel Form Development Phases I: 5 mo Data Collection OCT03-FEB04
Give ASTB and =1 of 8 prototype tests to 400 students each plus an AFOQT/ASTB sample
At 1 test/student, required N at 400/prototype was 3200
Data collected from 18 sites including NASC, OCS, NROTCs, USNA, & TBS
17. PF Data Collection Effort
18. Parallel Form Development Phases II: 3 mo Data Analyses Mar04-May04
Compared current ASTB scores to prototype scores
Created 3 new forms of Math Skills, Reading Comp, Mech Comp, Spatial Appreception, & Aeronautical Info
Divided MVT into separate Math Skills & Reading Comp subtests
Created Aviation Supplemental Test (AST) using items types from other 5 subtests; AST scores are figured into ASTB score computation using a proprietary algorithm
Score components still: AQR, PFAR, FOFAR, & OAR
Stat techniques used to scale the new subtests means old scores (Forms 1 & 2) can be compared to new ones (Forms 3, 4, & 5)
(Note. BI will be reintroduced as part of full ASTB revision by FY09)
Compromise damage remedied
19. Parallel Form Development Phases III: 30 Day Transition JUN 04-JUL 04
New versions produced:
Test Books (Forms 3, 4, & 5)- new Forms measure same abilities as Forms 1 & 2, but content was reorganized
Test Answer Sheets
Examiner’s Manual
APEX Examiner’s Guide
Deployed JUN 04 to CNRC & MCRC sites
Deploying JUL 04 to NROTC sites
Deployed on APEX platform in JUL 04
20. ASTB Administration Policy Changes After release of new parallel forms there are two major ASTB policy changes:
No more field scoring of paper tests and no scoring manuals issued, all scoring by NOMI
Immediate official scores available through APEX
Lifetime limit of 3 administrations (Forms 3, 4, & 5)
Prior to 1997 2 time limit existed
Previous administrations of Forms 1 & 2 do not count toward this limit
Intervals between tests are 30 days after 1st exam and 90 days after 2nd; 30 days required between most recent Form 1 or 2 and any current form (3, 4, or 5)
21. Retest Analyses Summary Taking the ASTB multiple times do not generally improve scores, True for OAR examinees as well
People who take the ASTB multiple times before passing are more likely to attrite from flight training
Even people who improve on retest are attrite risks: AQR of 7 for a 5th time examinee does not imply the same aptitude that a 1st time AQR of 7 would
Conclusion - A 3-test limit will:
Maintain quality of accession pool
Limit test and item exposure
Still provides a chance to improve
22. Automated Pilot Examination (APEX) APEX is a computer-administered ASTB, with content identical to paper-and-pencil ASTB
Original version developed by NAMRL Aviation Selection Division 1995-2001
Original version used at 4 sites in CONUS for official ASTB administrations from 1998-2002
2002 CNET and CNRC agreed to sponsor development of APEX 1.0 for fleet-wide deployment
23. APEX Deployment Deployable to all ~150 permanent ASTB test sites, including NRDs, OSOs, MCAFs, USCG, & Military Institutes
Test administrators issued user ID, user password, & workstation ID remotely by NOMI
APEX also available on a temporary basis to non-permanent sites like deployed ships and remote units
APEX 1.0 successfully used OCONUS at Sigonella & shipboard in Jun03
24. APEX Computer Requirements (Unchanged for Version 1.1)
25. All FY05 ASTB O&M funds rec’d; out-year funding programmed into NOMI budget as a line item for the duration of the ASTB effort
Programming improved APEX delivery system
including capacity for computer adaptive testing and inclusion of PBMs and Personality Assessment
On-going Test Item Bank Development
utilizing NOMI staff, contactors, and NASC stashes
Establishing NOMI Test Facility (OCS/API)
space alteration complete

28. ASTB Job Analysis (Conducted by NAVAIR-TSD) Steps
Gather info from SMEs and existing job analyses for all platforms and programs
Develop draft JAQ consisting of task/KSA inventory to capture job information across pipelines
Revise JAQ and administer to incumbents/SMEs
Analyze JAQ responses & produce documentation
Payoff
Helps determine which PBMs should be used, and will maximize predictive validity
Provides basis for developing new criterion measures for use internally or by CNATRA
Identify similarities & differences across pipelines
Will tell indicate where a personality measure may help Job Analysis may provide incite to future pipeline selection criterionJob Analysis may provide incite to future pipeline selection criterion
29. PBM Candidates to Be Evaluated USAF’s Test of Basic Aviation Skills (TBAS)
IHMC MMS (formerly NAMRL’s ASCAT)
CogScreen (LCAC & UAV Selection tool)
PMT and other select PBM tasks Since there is only one spatial abilities task, we would like to investigate some other Psychomotor testsSince there is only one spatial abilities task, we would like to investigate some other Psychomotor tests
30. Performance Based Measures PMT and CogScreen overlap on critical measures (multi-tasking and spatial skills). However, it should be noted that the PMT tasks tend to be more tasking.
