It depends on how you are defining "relationship." I tend to think most high school aged individuals have not had enough exposure and experience to be capable of making an informed decision to devote all their time and effort to developing a serious relationship with one particular other person. So if you are looking at long-term commitment to a single specific soulmate, I am skeptical.

If your definition allows for high schoolers to find out what it feels like to be infatuated with someone, then to experience a different kind of bliss with another person, then to move on to another kind of situation - as long as it is healthy and respectful of all the individuals and personalities involved, I think relationships are an important part of the maturation process.

I don't disapprove of any healthy relationship.  As people in high school are inexperienced in such relationships, it seems there are more unhealthy ones than in later life, but that's just my perception.  Besides, learning how to relate to people on that level, and learning how and how not to treat a partner are critical life skills and part of a young person's education too.

If they do not become too serious, high school relationships are a positive and integral part of the maturing process.  Friendships, certainly, are essential to a person's growing sense of worth and self-awareness; first loves often teach people much about life--hopefully, not too much!  But, who does not remember with sentimental feelings that first summer romance, how important it seemed, how grown-up we felt, how broken-hearted we thought we would remain all our lives? We are all the better in some way for having held meaningful relationships in our youth.

Some high school relationships endure, and some don't, but I think they are an important part of growing up. As a teacher, I always tried to stay out of students' personal lives, unless someone specifically solicited advice. But I think the social aspect of high school is at least as important as anything I teach, and students grow and develop through relationships. I certainly don't think they are a thing to be despised.

High school relationships certainly have an important place in our lives.  If you are talking about romantic attachments, I would say that not many high school relationships last beyond graduation.  Just because they aren't a life long relationship doesn't mean they don't have their place.  High school romances teach us many things about relationships and about life.  High school friendships are equally important.  The further past high school you go, the more you will be likely to wish you still knew those people you met in high school.  Often, high school friendships are long lasting relationships.  They teach us how to be a good friend and what a relationship really entails.  I think high school friendships also help us find ourselves.  All in all, they are a very important part of growth and development.

I don't think high school relationships are bad as long as they don't interfere with the boys' and girls' education.  After all, getting an education is the main reason we go to school.  The socialization comes secondary.  If high school boys and girls can keep their priorities straight, there's no reason why they can't (and shouldn't) have good, healthy relationships.   

I guess what I'm saying is I don't really detest high school relationships unless they lead to the couple's downfall (teenage pregnancies, failing grades, poor job performance, problems at home).  But, I don't exactly encourage them either, for the same reasons. However, if young people show they can be sensible, responsible, and mature in something (like dating), they should be allowed (even encouraged) to do it. 

It really just depends on the individual, but I think by the time most students are junior and seniors they are ready to be a part of a relationship.  Most don't result in marriage, but like anything in life, it takes practice and  experience to develop an understanding of things.  Additionally, companionship is a big part of each person's emotional needs.

The word, "detest" is pretty strong. I would not say that I encourage high school relationships, as many people are not ready for a relationship at that age. However, there are many exceptions as well. So, I would say that it is a case by case basis. However, on the whole, I do not encourage high school relationships. I think it is better for people to mature on their own first. 

I certainly don't detest them.  Some of them turn out quite well.  I've been to the weddings of many people who were both my students in high school.  Of course, there are also relationships where the people involved are unbearably immature and should be separated at once.  Luckily, those tend to dissolve with age.
