Assistant Principal

 I am excited to join the 99th Street Elementary School family as Assistant Principal. I am a Los Angeles native, who is a product of the Los Angeles Unified School District. I was bussed through the Permit with Transportation (PWT) Program to Winnetka Avenue Elementary and Oso Elementary Schools in Woodland Hills. I then attended my neighborhood school, LaSalle Avenue Elementary School. I graduated from Bret Harte Preparatory Intermediate School and am a proud alumna of George Washington Preparatory High School. I  attended Howard University, in Washington, DC, for my undergraduate studies and earned a Bachelor of Business Administration, with a concentration in Accounting. When I returned to Los Angeles, I decided that entering the field of education would be more rewarding than working in the corporate world. 

With over 20 years of experience under my belt, I have served as a substitute teacher and taught first, third, fifth and sixth grades at LaSalle and Annalee Elementary Schools. Before leaving the classroom, I pursued my Administrative Credential and Masters in Educational Leadership from Pepperdine University. Because I wanted to expand my lense as an educator, I became a Math Coach for four years and and contributed to the academic growth of Mathematics instruction at Woodcrest Elementary School. Further broadening my ability to support the diverse learners in our district, I became an Assistant Principal, Elementary Instructional Specialist (APEIS) and did so  for six years. This provided me with the ability to give support for and to better understand the instructional and behavioral support necessary for students with disabilities. 

Coming to serve as Assistant Principal at 99th Street has been a great experience, so far. I look forward to supporting teachers and staff, students, parents and the community as we work toward becoming a California Distinguished School. With hard work and commitment, I believe it can happen for the students in this community.

When I'm not educating, empowering, and encouraging the students at 99th Street, I spend time baking, singing, and shopping...for shoes, in particular.

Three of my siblings attended 99th and three of my siblings worked as TA’s here at 99th. I graduated with a BA, received a Teacher’s Credential and a Masters’ Degree from Cal State Dominguez Hills. I also got a second Masters’ Degree from CUI. I began working as a Teacher’s Assistant at this school in 1994 and I fell in love with this school and this community. I taught at this school for about forteen years and this is my sixth year as a coordinator. I am happy to be here and to be at your service.

Instructional Coach
 My name is Courtney Moore, and this is my 16th year at 99th Street Elementary. I am currently the school’s instructional coach, and I was formerly an upper-grade teacher for several years. Teaching is my passion, and I will give my all to ensure that all students are college bound and career ready.
With the start of a fabulous new year, our 99th Street scholars are already being exposed to a variety of new learnings, and we want to be sure that their learning continues at home. Here’s how you can help:
Have your children talk to you about what they’ve read (or what you read to them), and ask them questions that require them to go back to the text to find the answers. This is a powerful reading strategy that ensures that scholars understand what they are reading. 
Each grade level has key math foundational skills that promote mathematical fluency. Ask your child’s teacher for practice resources they can use at home to work towards mastery of these standards, or feel free to stop by my office (Room 22) for math materials/resources you can use at home to work with your child. 
I look forward to a positive and productive new year!
