Effectiveness of CA. There is limited data for assessing the effectiveness
of current CA programs. Findings from the survey indicated that (I)
approximately 80 percent of the installations surveyed maintain some
statistics relevant to CA (e.g., numbers and types of clearances, numbers
of clearance suspensions and revocations, numbers of security violations,
or numbers of reported derogatory incidents), (2) relatively few derogatory
incidents are reported to the security office (see Table l), and (3) the
number of clearance suspensions and revocations is very small. Table 2
shows the number of clearance suspensions and revocations during the past
12 months for sites in the survey sample.

Notes. Estimates are based on information provided by installation
security officers.
The sample sizes for these analyses ranged from 48 to 54.
Ratings of overall program effectiveness by installation security managers
indicated that CA programs are moderately effective. The mean
effectiveness ratings were quite similar across service branches, with the
Air Force receiving the highest effectiveness among collateral sites and
the Navy receiving the highest effectiveness rating among SC1 sites. The
mean effectiveness ratings of SC1 and collateral programs were nearly
identical within the Army and within the Air Force, but within the Navy SC1
sites received much higher ratings than collateral sites.
