What are the 6 types of parent involvement?

Could you please elaborate on the six types of parent involvement that are often discussed in the realm of education? I'm particularly interested in understanding how each of these forms of engagement contributes to the holistic development of students and fosters a supportive learning environment. Additionally, are there any specific strategies or techniques that educators can adopt to encourage and facilitate these types of parental involvement? I'm eager to learn more about the practical applications and benefits associated with each type of involvement.
