Absenteeism   The ratio of workers with absences to total full-time wage and salary employment. Absences are defined as instances when persons who usually work 35 or more hours per week worked less than 35 hours during the reference week for one of the following reasons: own illness, injury, or medical problems; child-care problems; other family or personal obligations; civic or military duty; and maternity or paternity leave.

Achievement Test The annual Pennsylvania System of School Assessment (PSSA) is a standards-based criterion-referenced assessment used to measure a student's attainment of the academic standards while also determining the degree to which school programs enable students to attain proficiency of the standards. Every Pennsylvania student in 5th, 8th and 11th grade is assessed for their reading and math abilities, and all students in grades 11 are assessed for their writing ability.

Average Cost   Referring to utility usage, this is a method of determining the cost of providing a service, generally power, to the various customer classes.  Average cost-of-service figures may be used in setting rates. Average costs are determined with the aid of information gathered in a cost-of-service study. Average costs are total costs divided by the number of units produced. This method of costing, while distinguishing costs between different customer classes, fails to recognize that not all kilowatts and kilowatt-hours are produced at the same cost within one customer class. Seasonal, time-of-day and marginal cost-based rates more accurately reflect the true costs of producing each kilowatt or kilowatt-hour.

 

Average Demand   The total demand for water/sewer during a period of time divided by the number of days in that time period. This is also called the average daily demand.

CAA   Clean Air Act. The primary federal law governing the regulation of emissions into the atmosphere. Originally passed in 1963, it has been amended several times with major changes occurring in 1970 and 1990. In 1970, primary responsibility for administering the CAA was given to the newly created Environmental Protection Agency. This act required promulgation and ongoing enforcement of National Ambient Air Quality Standards and National Emission Standards for Hazardous Air pollutants, which limit the maximum local concentrations of various air pollutants. In addition, the act limits the amount of various pollutants that vehicles may emit. The 1990 amendments set stricter provisions for motor vehicle emissions, attainment of the national ambient air quality standards, and specific restrictions on use or emissions of chlorofluorocarbons, NOx, and sulfur dioxide (SO2). The SO2 restrictions involve a system of tradable emissions allowances.
