Six specific issues affecting the progressive modification of neurobeh
avioral test batteries used in field studies of populations exposed to
neurotoxicants are discussed and test review recommendations are prov
ided addressing each issue. The issues include: (a) general test revie
w standards, (b) comprehensive assessment, (c) tailored batteries, (d)
incorporation of new tests and techniques, (e) personnel and mechanis
ms for review, and (f) development of a battery assessing peripheral n
