First sentence 2nd quote. 'Many more people...' I believe many can look at a cell phone for a quick moment.
If you can look at your phone, you can see that the call was from your school.
I do agree schools and parents need to agree on a good means of communication for the best interest of the child.
And there is new technology that could be easy to use, cost effective, and beneficial. Just saying "this is the way that has been used for XX years" is not a good answer.
In a school district of almost 200 schools serving almost 200,000 pupils serving who knows how many different languages, it's not a matter of parents and schools coming to an agreement. Its also not cost effective or easy to implement new systems. So unfortunately, the schools do have to say "this is they way that has been used for XX years, and until we implement a new system that we know will work for everyone of our 200,000 students, this is what we will continue to use. Parents need to know our methods and figure out how to make it work for them." With the number of students, giving each a specific parent-preferred-method of a communication is inefficient.
And if the caller id does not identify the phone call as "So and So School" I won't answer the call at all. It will go to voicemail where I may or may not choose to listen to it.
Seeing as your kids are in a school for multiple years, I would think that 1) you would have it in your contacts, or 2) you would recognize the number.
A text would be easy-and the Remind texts (just got one) identify the teacher and class. If I received a text of "This is Mrs. Smith at So and So School. We need you to call please, as soon as you can." I guarantee a parent would be on that pretty quickly.
I would be all over a missed call from the number (123) 456-xxxx because it was close to the number of my school.
Our district recently hired a well respected TV reporter as their PR director. She has implemented many improvements in communication district wide. Our district has an app, a Facebook and a Twitter. Push messages about school closures and important info for the district is sent out across all means to reach the maximum number of families. All of the schools have Facebook and a messaging service that is used by administrators for school wide announcements. It is important for districts and schools to modernize their communication methods.
Yep, all the schools in our district, as well as the district overall have all of the above. They are great to send out mass communications - snow days, etc.
