This school does nothing about bullying and harassment, and also doesn't do anything about the messy environment. If they try to do something about it, it barely helps. The teachers usually have a blind eye around bullying and kids don't get punished enough for bullying. The teachers also harass students as well for doing stuff slightly incorrectly.

This school is so bad. I have been in this hell for 3 years and got bullied for 3 years straight. Every single time I report it the staff does nothing and never believes a word I say. I also went to the principal and told her how every SINGLE one of my teachers were being disrespectful. The principal said that it could not be all my teachers. I swear to god it was all my teachers and I was getting treated worse and worse. No one is kind here and I mean it. The bullying made my mental health worse and the mental health team don't help at all. They never believe a word I say and it seems like they don't want to deal with me. I have no one to vent too and I do not feel safe at all being here. I am still a student here but I'm going to high school soon and I just want to warn the people that are reading this that you will regret coming here, I suggest you go somewhere else. This is Mercer's true colors it's not this one good school where they put bullying prevention and stuff but don't even try to help. The staff just want to deal with nothing and also the teachers don't even teach but talk to the bullies as if they were nice. I don't even know why I have been discriminated here let alone for 6 years now. I have to be in a unwelcoming and unsafe environment for 3 years now and I am so done. I can't even talk to a teacher without getting yelled at and when I tell this informations to the staff they again don't believe me and roll their eyes at me I'm not joking. I never felt heard. I always wanted to know why I get treated like this and by the way I don't just get treated like this it's a lot of students that are getting treated like this. They don't care about me at all and they go like "No we care" But doesn't your actions speak louder than your words. I swear to god no one in Mercer cares. They did nothing to support me academically and emotionally. They get worse with you every single time you report it and talk about it and literally have meetings with my parents about it. They lie. I don't. But they say the opposite of that. I know that they are not going to change at all but I just wanted to let you know I get treated like trash and they treat me as if I am worthless with no value. The staff and students make fun of me a lot. I don't even know how the principal is not ashamed of herself and her employees. You guys should be because I am not staying quiet anymore. I want justice for the 3 years of hell I had in this stupid school. Please do not come here.

Both of my children were bullied at Mercer even after much communication with Principal Diehl and counselors. They knew few people because of rezoning from the elementary students they grew up with from K-5. Both kids went to therapy and had major anxiety because of being afraid to go to school. The Dean only told me to email vs look at the cameras on all 3 physical incidences. They did not want these reports in their records. Mrs. Diehl seemed to be a great leader, otherwise.

This school is awful. There are probably the worst teachers and students ever. My son was beat up by some kids and now he goes to thearpy. My son also was made fun of by his counselor and teachers for his grades. He was treated awfully and now he asked to homeschool for the rest of his life. Parents DO NOT send your kids here. They will be traumatized . Mercer Middle School peers and what my son calls betas. My son is the true skibididi sigma alpha male. I hate this generation!

Very caring staff and a Principal and Assistant Principals that love the students and have high expectations for them. The school, like all schools has some students with discipline issues, but between the admin team and the Head of security, they deal with what they know about. Have always been available when I've needed to discuss anything good or bad. I love the place. My kids love how the staff engage them in the hallways with high fives and encouraging words. My kids enjoy being there and it always makes for good dinner time conversations. So glad all of my kids have gone or are going to Mercer. Keep up the great work Ms. Diehl and MMS Staff! You have our families full support.

I really don't know what to say!
Sometimes I feel like I don't feel safe in this school-I mean some of the teachers are nice but some are short tempered and just start shouting at you.
like today some kids were walking home when me and the group of kids reached the intersection and some other kids behind us were chasing each other. The substitute crossguard saw them and called them over, and guess what he did!? He sent a message to the principal so the three kids can have a meeting with him tomorrow!!! Why didn't he just give them a warning? isn't that a little harsh?-I mean their just middle schoolers just trying to have fun.
You parents just won't believe your ears, only your eyes?

Everyone disrespects me and doesn't care about my mental health. The nurse and teacher yell at you and accuse you of skipping when you are in pain in the restroom and feel that it's hard to get to the next class. The students are extremely rude and have no respect. They write inappropriate stuff in the stalls and blame it on the good students who never had ISR. If I come back home and get in a bad mood over this stupid school, then I will start listing teachers names.

The leadership is affective because it tries to get the students oppinion and is a big part of the school.

Posted: July 7, 2020

Yes they are constently encureging students to respect all people and does very well making sure all student profit from classes.

Posted: July 7, 2020

yes bullying is hardly a problem at Mercer and when it does arise Mercer staff and students deal with it effectively due to Mercers exstenceve efferts to teach students and staff how to avoid bullying others and how to stop bullying when they see it.

Posted: July 7, 2020

I am a student at Mercer and I absalotly love it. The staff are kind and supporteve and respect all student. The teachers try to make lessons fun and engageing and that all students profet from lessens. The students are kind exspesaly due to the exsensive efforts of the school to teach them good idels and most student take in these lessons an use them all the time bullying is not a problem at Mercer and the students are kind. teachers try their best to help students manage their work load and are very supporteve. They're dozens of clubs for students to pretisapate in and Mercer has opptions for all types of students. I love it there and can't wait to return for my eiath grade year.

Posted: July 7, 2020

They give only homework so it is very easy for us students to do it on our home wok and they don't give a lot of homework in the first place.

Posted: July 7, 2020

The teachers are very supportive and try very hard to make lessons fun and engaging for student so all student can learn

Posted: July 7, 2020

Yes respect integragy and commpashion are big things at the school and they press these values hard and most student take to them and amplafy them

Posted: April 6, 2020

Mostly negative. Thankful we are no longer zoned here.

Posted: April 6, 2020

Posted: April 6, 2020

Disagree, even the leadership does not listen to the kids. And since some kids don't even know who his after being there almost a year - I flows back to the leadership.

Posted: June 1, 2019

The leadership is a non-entity - never seen, never heard from. Totally generic emails are sent via connect-ed - NO interaction with the students or parents. Our 3rd middle school (boundary changes) and this leadership is the horrible.

Posted: June 1, 2019

Posted: June 1, 2019

Posted: June 1, 2019

Not a great school teachers are solely focused on SOLs and that comes from the leadership as they are in fear of losing their jobs and tell the kids so. Horrible experience there are much better run schools in LCPS. So sorry we have to stay for another year until Willard is turned back into a full middle school (what a horrible fail on the school board's part).

My experience with discipline on the school bus has been very negative. Some students on the school buses are out of control and bully other students constantly. This has been reported to the counselor and there has been no change. The school needs to do more to stop the bullying and obnoxious behavior on the buses!

If I had another option to choose for my child, she would not attend Mercer. The school is extremely overcrowded so my daughter has to be bussed to the High School. This was an intimidating experience for my daughter. Mercer teachers focus instruction on successful Virginia standardize testing / Standards of Learning (SOL) scores instead of learning curriculum. Stress from SOLs in addition to heavy homework/projects has caused unnecessary stress for my student. Music teachers require after school classroom practice and performances as part of students grade. Very limited extracurricular classes and programs. No sports teams. Traffic in/out of the school is crowded in the mornings.

Mercer Middle School is the best! My girls love the school. The principal, Mr. Robert Phillip is a great leader. I see him at every single school event. He is very involved and cares very much for the Mercer kids. The Assistant Principle is Mr.Cottone . He is just a mirror of Mr. Phillips. They both work very hard to provide a wonderful environment for the Mercer kids to strive their best while having fun doing all the extra curricular activities. The couselors, Mrs Miles and Casterline are professional at what they do. They put the smiles on their faces every single time I see them and trust me I am there a lot. Also the front of office staffs are kind, friendly, and professional. They even came and supported the students on one of the fundraiser nights!! Last but not least, the wonderful Mercer teachers. They work very hard and are very good at what they do not only in the classroom but also shaped the kids to be good citizens beyond the classrooms. They take on other responsibilities like teaching for a cooking club or being a coach for the volleyball club. My kids are fortunate to get to experience them all.
As my kids are leaving Mercer this year, I want to take this opportunity to thanks each staff and teacher at Mercer. Words can't express enough our appreciation of them.

Posted: February 23, 2017

The teachers don't care about the students. The school is overpopulated by almost a full thousand students which has resulted in drugs, fights and other misdemeanors.

Posted: December 20, 2016

The overcrowding, resulting in kids being bussed to the Mercer Annex at John Champe has not been a good experience for my child. As in any school you have good teachers/ staff and not so good. Communication is an issue. Overall its an average middle school in Loudoun County if you are looking for exceptional - this is not the place

Posted: March 10, 2015

I'm currently a student at this school, and I can say, it's great. The teachers are helpful and the students are friendly(it's easy making friends here). Overall, this school is excellent. I highly recommend you sending your child here.

Posted: February 4, 2015

Great school! I love the way the kids are grouped by teams and there are "wings" in the school for 6th, 7th, and 8th grade so it is easier for the kids to get around. The teachers are very helpful and I love using Clarity to keep up with my child's grades.

Posted: January 12, 2015

My child is new to the area and has been welcomed with open arms by the staff and faculty. This means so much to us. We could not be happier with Mercer Middle School.

Posted: September 8, 2014

I have had three of my children attend this school. Mr. Phillips is truly vested in the success of the school. Parents are encouraged to participate in any school activities. The guidance and counseling staff are exceptional. I believe the kids that have written negative reviews may just not like middle school, any middle school. I could not recommend Mercer any higher!

Posted: August 23, 2014

Our daughter is going to be in 8th grade and she loves the school and teachers are great and supportive.

Posted: May 22, 2014

Mercer is great! I am in sixth grade and will be staying until 8th grade! All the negative reviews are not true and it has very good teachers and very good discipline! Mr. Philips is on top of everything and I love all the clubs! I have made so many friends here too! 2013-2014 is it's most recent year and is the best! Love this school! Best in Loudoun!

Posted: April 22, 2014

My son goes to this school and has had a very positive experience so far. He enjoys his teachers and his classmates. I hear the same from his friends. I'm surprised by the negative reviews.

Posted: January 7, 2014

I hate it and I can't get out. I feel bad for my friends here to. Everyone is so screwed up. I wish I never went here. It's torture

Posted: December 12, 2013

This is my sons 2nd year at Mercer and it has been a wonderful school for him. His teachers are responsive and helpful when issues arise. The new administration is working on getting it's sea legs and has demonstrated a strong leaning towards leveraging current technology. I have nothing but good things to say about this school and my son is very happy there - or as happy as any child going to school will be:-). He has participated in a number of the clubs(engineering, Lego Robotics) and is currently in two classes that will give him high school credit. I have been in the school quite often and don't understand why someone claimed it was dirty since it is well maintained and is less than 10 years old. -- submitted by an involved parent

Posted: August 25, 2013

My school is Mercer. A lot of the other reviews are bad, but that is most likely because it was a while ago. It is now the 2013-2014 school year. The teacher are all really nice and funny and would love to help you whenever you need it

Posted: May 9, 2013

I agree with the previous review by a parent that the administration sweeps problems (bullying) under the rug and retaliates against the parents. There is a huge disparity between the way some students/parents are treated by the administration over others. More professional development is needed across the board, especially with their Special Education staff. This administration takes no accountability for their actions. As a parent, I find myself trying to undo all the damage done to my kids by the school. Something is very very wrong with the administration. They need a total staff overhaul from the top down. I wouldn't recommend this school to anyone.
