Viewing the SAT as a Challenge and National Indicator
Viewing the SAT as a Challenge and National Indicator
in response to Washington Post article Your SAT Score Has Little to Do
As a Math peak performance coach, I have found that studying for the SAT can be challenging and entertaining while promoting brain fitness at any age. Although I graduated from college in 19XX, I took the SAT in 2009 to gain perspective, to have fun, and to boost mental fitness. I learned much reading and grammar while studying last summer.
Some fields of study use the SAT as a measure of being able to ‘keep up with the Joneses’. Engineering schools want high Math scores (to follow along with profs who write a dozen equations on the board); likewise, journalism schools want high verbal scores.
The SAT is important because there is no national standard of high school curriculum or a national exit exam. While the Core Standards have been in the works, the existing standard could be the SAT (or ACT or GED) as a unifier for a reasonable body of knowledge. http://www.corestandards.org/.
The GED is a formidable exam -- only 60% of high school graduates could pass the GED http://www.acenet.edu/Content/NavigationMenu/ged/etp/score.htm
If people could view the SAT like a marathon, it would give mental fitness a boost!! Test taking/studying just makes you smart just like working out makes you physically fit.

Math Would Help People Land Jobs
Workers Need Better Skills
American workers need 9th grade level Math to gain jobs in the manufacturing sector. One of the slides shows 8th graders on a tour of a factory.
