Condensed Norms: ACS Cooperative Examinations Five new tests were publiShed by the Examinations Committee in 1969: Qualitative Analysis Form 1969, Physical Chemistry Form 1969, Inorganic Chemistry Form 1969, High School Chemistry Fonn 1969, and Graduate Level Placement Examination in Analytical Chemistry Form 1969-A. In addition to the norms for the 1969 tests, the norms for Brief Physical Chemistry Form 1968B are presented. Data for the Qualitative Analysis Form 1969 are still being collected. The condenred norms presented here are selected from a. larger body of data. which may be obtained from Examinations Committee-ACS, University of South Florida, Tampa, Florida 33620. Condensed norms for other currently used American Chemical Society Cooperative Examinations have been published in THIS JOURNAL, 37, 166 (1960); 38, 211 (1961); 39, 151 (1962); 40, 144 (1963); 41, 166 (1964); 42, 170 (1965); 43, 217 (1966); 44,243 (1967); 45,273 (1968); 46,182 (1969).

The testing program of the Examinations Committee continues a high level of rtctivity. Virtually all of the subcommittees are currently engaged in writing new tests. An Inorgenie-OrganicBiological test is currently being developed for use with psrsi medical programs. I n addition to the four new tests beingintroduced, thirty-eight other tests are also featured in the current testing program.
N m tests published for 1970: General Chnistry Form 1970: a 105-min examination reflece ing contemporary ideas in the weas included in today's firstyear college chemistry courses. The test items are based on principles and calculations in the broad categories of atomic and nuclear structure, molecular structure and bonding, stoichiometry, acid-base theory, equilibrium, kinetics, states of matter, electrochemistry, thermodynamics and descriptive chemistry. Quantitative Analysis Form 1970: a 90-min examination dealing with such-topics as separations, statistics, and volumetric, gmvimetric, electrical, and spectrophotometric rtnalysis. There are questions de$ing with the choice of the best method of analysis for several analytical samples. Inorganic Chemistry Form 1963: this 115-min examination has been updated with the publishing of the 1970 version of Part 11. Part I of the test consists of 60 ohjective questions. Eaoh version of Part I1 (1969 and 1970) consists of 5 questions requiring essay-t,ype response covering structure, bonding, thermodynamicg, coordination chemistry, and synthesis. The 1069 and 1970 versions of Part 11, a.well as Part I, are included wibh each test booklet. A 1971 version of Part I1 will be published next fall. Adoanced High School Chemistw Form 1970ADV: an 80 min examination which is in two parts. Part I covers areas of atomic structure, bonding, kinetic molecular theory, electrochemistry, kinetics, equilibrium, and thermodynamics. Part I1 is applications and calculations based on the principles covered in Part I. The test, designed for advanced high school chemistry courses, may also he used as a placement test for students entering university or college.
