” - - hearing subject’s performance on the mathematical problem-sovling task was consistently higher than their deaf peers accross all educational levels. The deaf baccalaureate students exhibited the highest performance of all the deaf participants but only performed at the level of the hearing middle school students who were the lowest scoring hearing group.”

”The deaf children found it relatively difficult to use the inversion principle. Their scores in the basic inversion problems were significantly lower than those of a comparable gorup of hearing children. - -Deaf children’s entry into school is delayed.- - The intervention group out-performed a control group both in an immediate post-test of the understanding of the logical principles and, about 1 year later, in the government administereed mathematics achievement tests.”

” - - deaf students’ English and reading skills, as well as their knowledge of mathematics and science, suggest that they are considerably under-prepared for advanced studies at the postsecondary level. At entry to college, only about 20 % of deaf students meet or exceed the college readiness benchmarks for English and reading. For science reasoning and mathematics, only 10-15 % meet or exceed c.r.b.
