My two children, ages 4 and 6, started at SVS in September 2014. I put them in this school because 15 years ago, it transformed my brother from a miserable high school drop-out to a happy, confident honors college graduate.
My children initially experienced great benefits from being at this school. At their old school, they did not get enough time outside, they were often forced to endure collective punishment (where the whole class is denied recess because of a few rowdy kids), and they always had to work on whatever the teacher directed. Thus, my oldest child went from absolutely LOVING math to deciding she didn't like math, because the teacher was always forcing her to do it when she wanted to be doing something else. Studies show that students who are taught math every year from first through sixth grade do no better, and sometimes worse, than students who receive one year of math education in sixth grade.
At first, at SVS, my children thought they were free to learn what they chose to learn, and their innate love of learning resurfaced. Instead of having to force them to do homework at night, they voluntarily did hours and hours of homework every night. They don't think of it as homework. They taught themselves to read by writing letters to their cousins. They learned math by counting days on the calendar until holidays, or planning their allowance purchases. They came up with every imaginable kind of creative project - science projects about dinosaurs, gardening, outer space, the sea, wilderness skills; carpentry projects; elaborate physics projects with balls and swings and slides; Baking and cooking projects are teaching them fractions and chemistry; they asked for books about historical figures and ethical issues, write stories, act out plays, make up songs to sing and play on the piano - their desire to sit and watch TV was far lower than it had ever been.
Also, they became much stronger - the six year old went to the park and competed in some informal races. She won every race, even against boys who were two years older than she. Today's children have far less "core strength" than is considered healthy, because they sit all day. My children are strong and healthy; they move their bodies all day, except when they choose to sit and become absorbed in some sort of project.
Yes, some kids will go through phases when they just want to play video games. Then they usually realize there is much more to life.
Some staff at SVS are caring, compassionate, and incredibly conscientious about the safety and well being of students. Other staff are manipulative, deceitful, and shame students terribly.
Some students are also very caring and conscientious - they look out for each other with great empathy. Other students are terrible bullies. Sometimes the school protected my little ones from bullies. Other times, it did not protect my children from bullies, and my children became terribly stressed by the relentless bullying and the staff denial. We left the school due to the repeated inability of the school to protect my young children and their friends from several vicious older bullies.
There are 50 years worth of data to back up the success of self-directed education. And there are many options available now for models of self-directed learning. SVS had a great idea, and it used to be fantastic. Unfortunately, it has changed quite a bit and lost sight of its vision. Thus, many families have left the school in recent years-- not because they do not understand self-directed learning, but because they do.
But this school still works well for some kids. I recommend it to anyone who is savvy enough to avoid criticizing the staff or the judicial system of the school, because that will not go over well. But if your child can handle bullies without help or support, does not want any mentoring or much interaction with staff, or keeps to herself/himself and never needs much, s/he might have a great experience here.
