CLC Case Study Background Introduction

I work as a data analyst for a Cobblestone Learning Center (CLC), which offers tutoring services and test preparation courses to students in grades 7-12 across different areas.

​

School Districts Served:

Beaverton, Camas, Lake Oswego, Ridgefield, Riverdale, Sherwood, St.Paul, Wilsonville

Programs Offered: CLC offers three programs: SkillsAdvantage, Cobblestone Refresh, and One-on-One Tutoring. All the programs are offered in-person, and Refresh and Tutoring courses are offered online.

​

Student Assessments and Progress Tracking:

•     CLC has a four-part general assessment for tracking student progress.

–     The general assessment includes a reading, writing, "calculator" math, and "no calculator" math component.

–     The writing score is on a scale of 100 points.  The other three scores are each on a scale of 800 points.

•     When students first enroll at CLC, they take the general assessment and their scores are recorded as “intake”, or baseline, scores.

•     Every time a student completes one of CLC’s programs, they re-take the assessment and their scores are added to their student assessment record.

​

My job is to analyze the student assessments database to give business insights and recommendations to better serve CLC’s clients and better steer its business strategy.
