A responsive answer sheet for use in educational testing en-
* vironments is disclosed. The answer sheet consists of a
* recording surface containing a plurality of indicia that are

4 associated with responses to a knowledge-testing format.
I The indicia is overcoated with a non-imagewise layer of
light-occluding material in the form of a particulate xero-
graphic toner. An example of toner that can be used is a
copolymer of styrene and n-butyl methacrylate. The toner is
* in a form of only being partially fused to the underlying
indicia and surrounding recording surface. Preferably, the

4 overcoating toner layer is affixed to the underlying indicia and recording surface by a fusion bond representing between a class 1 and a class 2 fix which is sufficient to provide
handleable copy and insufficient to prevent removal from the indicia whereby a user may render the indicia visible

by abrasively removing only the overcoating layer of toner.
