These correlations are very high. In a previous study (Rumsey, Osborn,<br />

&,Ford 1985) the authors looked at correlations between hands-on and written<br />

tests for 28 occupations in which the overall correlation for the 28 jobs is<br />

.41. Selecting the eight occupations that are similar to the Radioman, the<br />

hands-on--written correlation is .45, and for the military job most like the<br />

Radioman's --the Army Radio-Teletype Operator--the correlation is .37. Again,<br />

much of the notable results for the Radioman in this area is believed to be<br />

directly a result of the high rater reliability performance.<br />
