An increase in enrollment has resulted from the revised mathematics and science requirements. The mathematics requirement now demands at least two years of mathematics incorporating algebraic and geometric thinking.
Science now consists of two years focusing on physical and life sciences.
Such requirements have resulted in an increased enrollment in the related courses this school year and into the 1999-2000 year. In addition, a computer literacy requirement has also been implemented. All freshman are required to demonstrate computer literacy in word processing and on-line research. Willowbrook's lower completion rate is said to be due to a delay in putting the school's writing center On-line. The effects of additional adjustments to graduation requirements are still being monitored.
