Dental Admission Test (DAT).
In order to be admitted to dental school, an individual must do
well on the Dental Admission Test (DAT). This exam was developed by
the American Dental Association to measure academic ability,
understanding of scientific information, and perceptual ability. Individuals must have completed at least
one year of college, including courses in biology and organic
chemistry.
The Dental Admission Test is composed of four distinct
tests:
a survey of the natural sciences (90 minutes);
perceptual
ability test (60 minutes);
a reading comprehension test (60
minutes);
and a quantitative reasoning test (45 minutes).
There is
an optional fifteen-minute break between the perceptual ability and
reading comprehension tests. The survey of the natural sciences
includes the following specific topics in biology, general
chemistry, and organic chemistry: cell and molecular biology;
diversity of life, biological organization, and relationship of
major taxa; vertebrate anatomy and physiology; developmental
biology; genetics; evolution, ecology, and behavior; stochiometry;
gases; liquids and solids; solutions; acids and bases; chemical
equilibria; thermodynamics and thermochemistry; chemical kinetics;
oxidation-reduction reactions; atomic and molecular structure; periodic
properties; nuclear reactions; laboratory procedures; mechanisms of organic
chemistry; chemical and physical properties of molecules and organic analysis;
stereochemistry; nomenclature; individual reactions of the major functional
groups and combinations of reactions to synthesize compounds; acid base
chemistry; and aromatics and bonding.
The perceptual ability section of the exam includes angle
discrimination, form development cubes, orthographic projections,
apertures, and paper folding.
The reading comprehension section consists of passages on
dental and other sciences, which the candidate will be required to
evaluate.
The quantitative reasoning section of the exam consists of
math problems in the following areas: algebra; numerical
calculations; conversions; probability and statistics; geometry;
trigonometry; and applied mathematics problems.
The candidate will receive a copy of his or her score report at
the testing center immediately after finishing the exam. The testing
center will also mail copies of the score report to the pertinent
dental schools.
scores are standardized onto a scale of 1 to
30.
Exam score is based on the number of questions answered
correctly, so candidates are encouraged to guess on questions they
do not know.
The Dental Admission Test is administered by Thomson Prometric; those interested in taking the exam should visit the
