Arrival and Dismissal Procedures


  • The pedestrian gate opens at 7:25 a.m.  If your child arrives prior to 7:25 a.m., your child will be on the sidewalk unsupervised.
  • Do not send your child in through the driveway gate; this is very dangerous.
  • Follow all posted city signs so children can be safe when entering school.


  • The pedestrian gate opens at 1:24 p.m. on Tuesdays and at 2:24 p.m. on all other days.
  • Please do not block the yellow walkway while you are waiting in the parking lot.
  • Please supervise your younger children while walking through the parking lot and remain in the yellow safety walkway.
  • No children should be playing in the parking lot, in the offices or on the stairs or left unsupervised after the bell rings.
  • If you have elementary and middle school students and you pick them up, then you can wait for the second dismissal in the park; there is no waiting on campus.
  • If you have a K or 1st grade student, you can enroll them in LACC (see Ms. Gudino), the Boys and Girls Club, Ramona Hall, Montecito Heights, etc. They cannot wait for their middle school siblings for 39 minutes unsupervised.
  • If you have 2nd-5th grade students who are waiting for their middle school siblings, you can enroll them in EYS (see Ms. Lira).  They cannot wait for their middle school siblings for 39 minutes unsupervised.
  • If you have middle schoolers, after school they are either in a club, in intervention, in EYS, in LACC or in another program.  They cannot remain on campus unsupervised.
  • NO students can wait by the front gate unsupervised after school.  Every single child must be either enrolled in a program or on their way home at dismissal time.

Welcome to Arroyo Seco . . .

Arroyo Seco Museum Magnet School is a beacon for educational innovation and academic excellence.  From our unique magnet focus to the unequaled museum experiences it provides, we are committed to providing our students with a brand of elite academic preparation.  The hallmark of our success is not only limited to the intelligent, capable students we produce but it is also found in our remarkable corps of highly qualified, dedicated and caring faculty and staff.

As our reputation for academic excellence has grown, so has the prospective interest.  We recognize the special gifts and talents of every one of our students and work diligently to help them realize their potential as future leaders and innovators of the world.  Our students will go on to enjoy the privileges earned by their individual achievements but will do so with a motivation greater than material reward.  Arroyo Seco Museum Science Magnet strives to produce talented, thoughtful leaders capable of entering the world on their own terms and leaving it better for us all.

"I believe profoundly in the importance of museums; I would go

as far as to say that you can judge a society by the quality of its museums.–R. Fortey


In Museum Science Studies courses students will learn the roles that museums play in our society. They will learn about specific museums.  They will learn why they were created and how they are funded, managed, and organized.  Students will visit and evaluate museums in Los Angeles, including virtual exhibits.  They will develop analytical and critical skills by reading, discussing and debating different museum exhibit collections.  Student will have the opportunity to work directly with staff from the Autry National Center to learn the seven key roles that museums must fulfill in society and the types of jobs that can be found in museums.  Once students have a strong foundation in California history, they will begin working to develop a field trip program for fourth grader students in Los Angeles area schools.  They will provide history tours of the Casa de Adobe, a replica of a traditional California rancho home.

Free Museum Days in Los Angeles

Today: 8/18/18


August 15, 2017


Dear Parents/Guardians:


On behalf of all of our staff, I welcome you to the 2017-2018 school year!  We welcome Mrs. Angelica Garcia, TSP Coordinator, Mr. Christian Perez, Building and Grounds Worker, Mr. Bryan De Leon, Teacher Assistant, Ms. Nathalie Ramirez, Teacher Assistant, Mr. Arlen Ruelas, Teacher Assistant, Mr. Jason Ruiz, Teacher Assistant and Ms. Brach Cabral, 6th grade Math/Science teacher.  We wish Ms. Laura Tovar the best as she transfers to Nimitz Middle School. 

Today, your child will receive a large white envelope with information for you to read, keep or return.  For your child’s safety, read the entire contents of the envelope and return all forms by Friday, August 25, 2017.  It is extremely important that we have emergency information for your child. 

Students in grades 2-8 will receive a Daily Agenda (planner) for communication between the school and home and to help your child organize and plan his/her studies.  Be certain to review the Daily Agenda every day.  Parents will be informed about school events and activities through monthly newsletters, fliers, phone calls and on our website at http://arroyoseco-lausd-ca.schoolloop.com/

Our academic focus this year will be on the Next Generation Science Standards and how they relate to Museum Science and, of course, literacy and numeracy.  I am excited that all students, grades K-8, will have the opportunity to visit the Huntington Library again this year.  Additionally, we are excited that our Visual Arts teacher will be here two days a week and our Music teacher one day a week for the entire year.  The opportunities for connections and learning and growing our knowledge of Museum Science are endless. 

We will be establishing our Local School Leadership Council, ELAC and SSC in the next month, as well as holding our Back to School Night on August 22, 2017.  Please feel free to contact us at 323/254-5141 or via email at robin.polito-shuffer@lausd.net if you have any questions. 


Thank you and I look forward to meeting you at Back to School Night!


Robin Polito
