  This paper is written as one chapter in a collection of essays on neutrino
physics for beginning graduate students. The text presents important
experimental methods and issues for those interested in searches for sterile
neutrinos. Other essays in the collection, written by other authors, will cover
introduction to neutrinos in the Standard Model, a description of the theory,
and discussion of details of detectors, thus these aspects are not covered
here. However, beyond these points, this represents a self-contained tutorial
on experimental studies of sterile neutrino oscillations, covering such issues
as signals vs. limits, designing experiments, and performing and interpreting
global fits to the oscillation data.
