Sociometric status is derived from a concatenation of judgments at the
individual level. In previous articles, the authors argued that score
attribution at this level (where one group member assesses another) i
s one-dimensional along the sympathy <----> antipathy continuum. Two-d
imensionality of sociometric statics arises at the group level. It was
shown that al this level too, sympathy and antipathy are not two dist
inct dimensions but the poles of just one, tile other being visibility
(or impact). If one accepts the model of one-dimensional score attrib
ution at the individual level, it would seem logical to base sociometr
ic status determination on rating scales. In this article, a procedure
for this is developed and a covering computer program (SSRAT) is intr
oduced. Finally, the results of the current nomination methods and the
proposed rating method applied in the same classroom groups are compa
red The results of the rating method appear to be more valid and more
refined.
