Lack of time is also a barrier that prevents parental involvement. Parents often cite time as the single greatest barrier to volunteering, attending meetings, and joining decision making committees at their children's school (PTA, 2009). Parents, who work in low-paying jobs that do not offer time off for illness or family emergencies, do not have a lot of time for parental involvement and they cannot risk their jobs to take time out to visit their child's school. There just simply are not enough hours in the day to accomplish everything (LaBahn, 1995).In today's society there are more single family households that require the parent to work long hours.With the increase in single-parent households and the dramatic change in the work force, with mothers of school-aged children entering in great numbers, time has become a valuable commodity for parents who struggle to make ends meet (Patrikakou, 2008). For example, many mothers do not have equipment or the skill to plan science fair experiments or construct woodworking projects, and fathers may not be able to help design and sew costumes for the school play.
