Parent Communication

This past year has been very busy especially in trying to continuing my goal of increasing communication with parents. Earlier this week I sent out a survey and have been surprised with the positive feedback that I already have received. I am still waiting for several parents to respond as 7 of them have already responded. I will be sending out a paper survey for a number of families that do not communicate with me through e-mail.
Even though communication has not improved some of my student behaviors it has helped create positive relationships in which I could go to parents without hesitation when a difficult situation occurred. I still need to improve communicating with parents but feel this year has been a step in the right direction. Out of twenty families in my class, I have about 1/2 of them that communicate with me regularly.
How can I get the other families on board to communicate more? When I call those families, I continue to get voicemail and those families often do not reply. This year I had my best turnout for parent teacher conferences as 100% of my families turned out this year. That has been fantastic. However, despite sending home progress reports monthly and conferences, there are still a few families that I have not heard from throughout the year. I would like to do a better job in reaching out to those families.
So far the parent survey has been positive and I am wondering how it will end up. Overall I think parents feel that it was beneficial so I am excited to see how the responses end up so I can make those improvements for future years. Along with my weekly and monthly parent letters, I do think the progress reports have given parents more information on things they can assist their child with at home.
