Law School Admission Test

The Law School Admission Test (LSAT) is a half-day standardized test administered four times each year at designated testing centers throughout the world. Administered by the Law School Admission Council (LSAC) for prospective law school candidates, the LSAT is designed to assess reading comprehension, logical, and verbal reasoning proficiencies. The test is an integral part of the law school admission process in the United States, Canada (common law programs only), the University of Melbourne, Australia, and a growing number of other countries. An applicant cannot take the LSAT more than three times within a two-year period.

The test has existed in some form since 1948, when it was created to give law schools a standardized way to assess applicants aside from GPA. The current form of the exam has been used since 1991. The exam has six total sections: four scored multiple choice sections, an unscored experimental section, and an unscored writing section. Raw scores are converted to a scaled score with a high of 180, a low of 120, and a median score around 150. When an applicant applies to a law school, all scores from the past five years are reported. As of June 2014, it costs $170 (USD) to take the LSAT in the United States, and $165 (CAD) in Canada.

LSAT (oxide)

LSAT is the most common name for the inorganic compound lanthanum aluminate - strontium aluminium tantalate, which has the chemical formula (LaAlO₃)_0.3(Sr₂TaAlO₆)_0.7 or its less common alternative: (La_0.18Sr_0.82)(Al_0.59Ta_0.41)O₃. LSAT is a hard, optically transparent ceramic oxide of the elements lanthanum, aluminum, strontium and tantalum. LSAT has the perovskite crystal structure, and its most common use is as a single crystal substrate for the growth of epitaxial thin films.

Background

LSAT was originally developed as a substrate for the growth of high T_ccuprate superconductors thin films, mostly of YBCO, for microwave device applications. The motivation for its development was to create a lattice-matched substrate with a similar thermal expansion coefficient and no structural phase transition over a wide temperature range, spanning from the high temperatures used for the growth of cuprates, to the cryogenic temperatures where they are superconducting.

Properties

LSAT has a Mohs hardness of 6.5, placing it between quartz and the mineral feldspar. Its relative dielectric constant is ~22 and it has a thermal expansion coefficient of 8~10×10⁻⁶/K. The thermal conductivity of LSAT is 5.1 Wm⁻¹K⁻¹. LSAT's (cubic) lattice parameter of 3.868 Å makes it compatible for the growth of a wide range of perovskite oxides with a relatively low strain.
