Aberdeen Proving Ground (APG) is a United States Army facility located near Aberdeen, Maryland in Harford County.  The installation spans across  72,500 acres, more than half of which is water or wetlands. There are more than 6,800 acres of improved grounds, nearly 300 miles of road, and more than 567,000 square yards of airfield pavement. The installation lies on two peninsulas separated by the Bush River.


APG is recognized as one of the world’s most important research, development, testing, and evaluation facilities for military weapons and equipment.  It also supports the finest teams of military and civilian scientists, research engineers, technicians and administrators. It is the Defense Department’s Center for Excellence for land combat systems, vehicles, Soldier systems and chemical and biological defense.


Test and support facilities allow instrumented firing of weapons on a variety of state-of-the-art ranges, testing of tanks and other tracked vehicles over specifically engineered courses, and a wide variety of laboratory-type investigations. Newly designed weapons and other combat material are put through the most grueling field and laboratory workouts conceivable.

In 2010, the majority of states, the District of Columbia, and the Department of Defense Education Activity adopted Common Core State Standards that provide a consistent set of educational expectations for students, regardless of ZIP code. When a family moves, a student’s education is often disrupted because the student may be forced to repeat material or learn at a different level at the new school. With common standards across states, this disruption will be reduced — of particular interest to military families. For more information, visit www.corestandards.org
