    Riverside Prep. Elementary School---- my kids love this school. I love that not only are the teachers super involved but the assistant Principal AND the Principal are super involved daily!!!

  • (1 year ago)

    My kids did great during their elementary years at R.P. but now that they're in high school I've decided after having continual communication and academic differences with the teachers staff and the Oro Grande school district offices we're going to move them to our local high school. I placed them at R.P. because the administrators and many of the teachers were members of our church and we felt due to the reputation they had in church that same character would follow into the way the school was ran. I was wrong- i.e.-my daughter struggles in math. We were contacted just before grades came out that she'd be receiving a low grade (we had no warning in time to address the problem beforehand) yet when we received her report card she had a "B". - Big Red Flag! The teachers struggle. Most of them are fresh our of college and haven't got a clue how to handle the human aspect of teenagers. They can't control the immaturity of their students. Bullying is an issue along with extreme foul language and sexual harassment. They bit off more than they could chew and I won't have my kids continue to be victims of the school's lack of character quality education and morals.

    This school is a joke! We heard so many acclaimed "project-based" success stories. We put our 2 girls (10 & 11). They took an educational placement test. The school would only take students at or above grade level. "Great!" We thought. After 2 years of dealing with 1st year zero trained teachers in project based teaching and no curriculum in the areas of math and english we pulled our girls out. Check riverside's math percentages....in the toilet. As a certified educator I had the training and resources to teach my girls after school in algebra basic math writing instruction etc. Recently the Superintendent and. Assistant super were fired. I witnessed many questionable educational and financial dealings. Research and observe with eyes wide open!

    Goodness gracious if you don't like the school just take your kids out. Put them in as you put it a "real school." Since most of the negatives come from parents take your child out make room for those on the waiting list...but of course if your kid was already kicked out or you were fired than I guess we know where all the hate is coming from. Fat checks family connections what the heck? Charter schools are not the Mafia they are an option another avenue for parents like me to take. Victor school district is struggling financially if you're so smart why don't you roll out some solutions rather than compare a school that is sending students to good schools including Harvard UCLA Yale Stanford ( that's right the proof is in the pudding not from your opinion thank goodness) and providing jobs for people that have school loans to pay and families to feed. Spend some time with yourself look in the mirror tell yourself you are beautiful and you don't need to hate to be validated. If your kids were kicked out well my kids haven't and my children are pretty eccentric. Teachers and schools are to educate the mind character is built in the home. Look within.

    I attended RP for two years and then Serrano for two years. I can honestly say that the RP teachers care a lot more about you as a student. Serrano is great but if you are having trouble or messing around and not doing your work you drown. At RP I had teachers calling and emailing my parents when I wasn't getting things done and they were always willing to work with me to get my grades back up. RP teachers really care almost to the point where I felt babied. But to say the school sucks because you had good grades and then had trouble at Serrano well it's probably because you are aloof to the efforts of people around you. Also RP doesn't give homework until you are an 11th grader or if you are in AP classes. So maybe you feel like it's easier because of that. But you can't hide as a student. The teachers know you know your abilities and get to know your parents. That's why RP's test scores are much better (822 vs. Serrano's 790). It's pretty simple.

    I've been reading about allegations that the teachers aren't really teaching the kids but are more concerned with the reputation of the school. Well I can say at least in my son's case I do not believe that is the case. He has been at Riverside Prep for three years now. He is in 6th grade. Prior to that he went to a well-known private school in Hesperia. He has always been an A student and continues that trend. His teachers have ALL been excellent. Each year he has a hard time deciding who is the best teacher. I was worried about him going into middle school at 6th grade but he has done better in 6th grade than in elementary. This school also has PLENTY for kids to do and get involved in. I think everyone's experience is different in every situation but if you do what you're supposed to like in anything this can be a very positive experience if you are a student. Keep it up Riverside Prep!

    Teacher do not know much of what they teach. Yes your kids are gonna get good grades the teachers are told to inflate grades to make the school look better. I slept in almost every class there constantly talking paying little attention and got B's. I switched to Serrano recently and had a rude awakening to what a real school is. NO THE PRINCIPLE IS NOT A GREAT LEADER. Only thing I've ever heard from him to a student was negative. I remember in 7th grade for a speech he made he said "I don't want your best... I want the best." Take that how you want but that's not very influential.

    The school itself is pretty good but the kids are absolutely terrible to each other. The teachers do nothing about it and bullying is a problem. All it is is gossip gossip gossip like the kids have nothing better to do with themselves. This school was a terrible mistake that started out with such high hopes. Sincerely Ex-Student

    Excellent Administration; Mr.Bell is a great leader and very hands on. Coach Baily is Great!

    Riverside prep is the best school I have ever been to. The teachers DO know what they are doing. I only know about 2 or a few kids being removed from the school. The teachers are the best and if they don't have a masters degree it's because they are still taking classes. I don't have any problems with this school. I don't know what your thinking if you say this is a bad school but compare it to the others. This one is very nice and so are the teachers. Many kids have been expelled from not following the rules and the teachers won't tolerate their attitudes. I can go on and on about how good this school is. Thank you riverside prep

    Riverside Prep is a top notch HD school. They support students every way possible. The discipline is excellent with each child signing a contract agreeing to follow the rules. Parents and students that can't handle rules usually leave with a bad taste in their mouths. But if you have a high achieving child that is willing to go to school to learn AND abide by high standards and rules RP is THE BEST school in the HD. Excellent teachers all around and a very safe campus. I couldn't ask for more.

  • (2 years ago)

    I haven't had any problems with this school. The teachers are very supportive and very accessible. I love their no tolerance approach to children who are not behaving. I think the parents that are complaining on this site have kids that are bad and uncontrollable...take your kids to an Adelanto school so they can act up.

  • (2 years ago)

    I agree with the person that posted on Jan. 8th!!!! These teachers and this school doesn't know what the heck they are doing! I thought this would be a great school but NO WAY!!! Don't believe that they are a great school. They turned against my child and made it so it looked like my child was bullying when the teacher and the other students were doing the bullying!!! Do not put your kids here

  • (2 years ago)

    I put my four children into Riverside Prep two years ago. There grades have rose drastically. I could not ask for a better education and caring staff.

  • (3 years ago)

    Oh correction they did delete the fake doctoral degrees from their teachers' web pages. However as far as a "new superintendent" that's a farce because the new person in charge is still in the extended family.! They just shuffled the cards a little no doubt to keep the state off their backs lol! Unfortunately "charter school" is all too often synonymous with "familly business" a way for charter school founders and their relatives to pay themselves fat salaries at the taxpayer's expense. Well parents if you don't mind that and all you care about is test scores go for it!

  • (3 years ago)

    This school is the greatest choice you could make. They do not tolerate bad behavior so your children will be very safe here. They have great projects as it is a project based school that you'll never forget. The teachers here are great. They are responsible and urge their students to do their extreme best. It is the best school that I have went to yet.

  • (3 years ago)

    The class sizes are less than 30 students. If you can find a school that could do better than that send your kids there ). It's a choice to attend RP and it would be your choice to leave. I honestly do not want unsupportive parents to voice their negativity to their children. As a result of this the students show disrespect to the staff.

    Pioneer University is now closed. We have a new Superintendent and he was not involved with Pioneer. We have a great staff and work very hard to make the students learning environment exceptional. Thank you for your positive support.

  • (3 years ago)

    Something fishy here..the charter school itself seems legit enough.but one of the guys behind it also runs "Pioneer University" down the street. This "university" is giving out PhD's which are worthless because "Pioneer University" is not accredited. All of the "students" of this "university" seem to be employees of the charter school. Apparently the mastermind in charge even thought of creating a "school district" which includes the "university." (And since when does a public elementary/secondary school district also include a university?) Well I guess you have to admire their ingenuity if not their ethics. And don't bother trying to find out anything about "Pioneer University" on the internet because they don't even have a working website lol!

    Great school; always know that my child is in good hands when get on bus. Also love the no nonsense approach to discipline I feel very secure and do not worry about my child while at school. The campus is growing and I know that I made the right decision when my child transferred to Riverside Prep 3 yrs ago. As far as Schools in the High Desert Riverside Prep is one of the best! )
