| Leiter International Performance Scale | A nonverbal (performance) test for measuring intelligence which contains norms for each age between 2 and 18; originally developed as a method of assessing the comparative intellectual abilities of Caucasian, Chinese, and Japanese children, but now occasionally used for assessing slow learners and those who are blind, deaf, or verbally handicapped.

| adansonian classification | The classification of organisms based on giving equal weight to every character of the organism; this principle has its greatest application in numerical taxonomy. Origin: M. Adanson (05 Mar 2000) |
| Angle's classification of malocclusion | A classification of different types of malocclusion, based on the mesiodistal relationship of the permanent molars upon their eruption and locking, and comprised of three classes; Class I: normal relationship of the jaws, wherein the mesiobuccal cusp of the maxillary first molar occludes in the buccal groove of the mandibular first permanent molar; Class II: distal relationship of the mandible, wherein the distobuccal cusp of the maxillary first permanent molar occludes in the buccal groove of the mandibular first molar, and further classified as Division 1, labioversion of maxillary incisor teeth, and Division 2, linguoversion of maxillary central incisors, both of which may be unilateral conditions; Class III: mesial relationship of the mandible, wherein the mesiobuccal cusp of the maxillary first molar occludes in the embrasure between the mandibular first and second permanent molars, further classified as a unilateral condition.

| aortic dissection: classification | <radiology> DeBakey: I ascending aorta to arch with or without descending aorta (30%), II ascending aorta only (20%), III descending aorta to thoracic aorta (50%), Stanford: A involvement of ascending aorta (regardless of origin), B aortic arch and distal aorta see also: aetiology mnemomics: 1 A.D. (DeBakey), A = Ascending (12 Dec 1998) |
| Arneth classification | A classification of the polymorphonuclear neutrophils according to the number of their nuclear lobes. See: Arneth stages. (05 Mar 2000) |
| artificial classification | <zoology> Classification based on convenient or conspicuous diagnostic characters without attention to characters indicating relationship, often a classification based on a single arbitrarily chosen character, rather than an evaluation of the totality of characters. (09 Jan 1998) |
| Black's classification | A classification of cavities of the teeth based upon the tooth surface(s) involved. (05 Mar 2000) |
| Caldwell-Moloy classification | A classification of the variations in the female pelvis; namely gynecoid, android, anthropoid, and platypelloid pelvis, based on the type of the posterior and anterior segments of the inlet. (05 Mar 2000) |
| Galton's system of classification of fingerprints | A system of classification based on the variations in the patterns of the ridges, which are grouped into arches, loops, and whorls (A.L.W. Or arch-loop-whorl system). "Arches are formed when the ridges run from one side to the other of the bulb of the digit, without making any backward turn, but no twist; whorls, when there is a turn through at least one complete circle; they are also considered to include all duplex spirals." The abbreviations used in making a record of fingerprint's are: a, arch; l, loop; w, whorl; i, loop with an inner (thumb side) slope; o, loop with an outer (little-finger side) slope. The ten digits are registered in four groups as follows, distinguished by capital letters: A, the fore, middle, and ring fingers of the right hand; B, the fore, middle, and ring fingers of the left hand; C, the thumb and little finger of the right hand; D, the thumb and little finger of the left hand. See: dermatoglyphics. (05 Mar 2000) |
| Rappaport classification | A histologic classification of lymphomas in use before the availability of recent methods for identification of B-and T-type lymphocytes. (05 Mar 2000) |
| vertical classification | <zoology> Classification which stresses common descent and tends to unite ancestral and descendant groups of a phyletic line in a single higher taxon, separating them from contemporaneous taxa having reached a similar grade of evolutionary change. Compare: Horizontal classification. (09 Jan 1998) |
| phenetic classification | <zoology> Classification based on degree of overall similarity. (09 Jan 1998) |
| Rye classification | Classification of Hodgkin's disease according to lymphocyte predominance, nodular sclerosing, mixed cellularity, and lymphocyte depletion types. Origin: Rye, NY, 1965 (05 Mar 2000) |
| cladistic classification | <zoology> Classification based on recency of common descent, i.e. Categories depend on the position of the branching points on the inferred phylogenetic tree. (09 Jan 1998) |
