How San Diego Unified Built a Paid High School Teaching Internship

San Diego Unified is now five summers into a paid teaching internship that sends its own teenagers into elementary classrooms — and, unlike many districts’ grow-your-own plans, it is publishing enough of the operating model for other systems to study. In a July 22 district story following this summer’s Teach Lead Reflective Summit, the district said interns from five high schools worked at 18 elementary schools in 2026, up from 22 students at two high schools when the program launched in 2021. Times of San Diego reported the same expansion from the summit at Crawford High, giving the program a rare mix of district documentation and independent confirmation.

The change is not just scale. San Diego Unified’s 2026 internship posting describes a five-week, paid program totaling 82 hours for currently enrolled district high school students who were at least 16 by June 10, 2026. Students could gain hands-on classroom experience with elementary children, professional development, leadership training and, if they chose, non-weighted elective high school credit. The internship sits inside the district’s broader TEACH-LEAD San Diego pipeline, which the district presents as a homegrown route into education careers. What the public materials highlight much less clearly is the long-term conversion question: whether early exposure is translating into eventual credential candidates or district hires at meaningful scale.

What San Diego Unified actually built

One reason the model is useful to other districts is that San Diego Unified did not leave the mechanics vague. The district said applications opened Jan. 30 and closed March 13, with interviews possible before final decisions and the internship running June 1 through July 2. On a separate Extended Learning Opportunities page, San Diego Unified listed five 2026 hub high schools — Clairemont, Crawford, Henry, Morse and Scripps Ranch — and said student workers would be placed at elementary schools in the cluster they selected. The same page spells out the kind of operational details that usually make or break youth employment programs: a professional reference, legal work eligibility and a firm summer commitment.

The work itself is also more defined than a generic shadowing experience. District coverage says interns spent their first five days in training with FranklinCovey coaches and two more days with career technical education teachers focused on professionalism and classroom management before moving into elementary classrooms. The Extended Learning Opportunities site says students were trained to deliver Leader in Me social-emotional lessons as assistant teachers. That kind of front-loaded training matters. It gives teenagers a bounded role, gives elementary sites a shared playbook and reduces the risk that a district markets a pipeline program while leaving classroom teachers to invent the job on the fly.

The program also appears to create a ladder, not just a one-off summer job. At the summit, both district coverage and Times of San Diego highlighted Kelly Padilla, a recent graduate of the San Diego School of Creative and Performing Arts who returned after last summer and served as a lead intern. That is a small but important design choice: districts trying to build educator pathways need visible ways for students to come back, take on more responsibility and imagine themselves in school-based work before college or credentialing decisions harden.

Why this version travels

Plenty of districts talk about grow-your-own recruitment as a college scholarship, residency or human-resources strategy. San Diego Unified starts earlier. The California Department of Education describes grow-your-own programs as a proven approach that in some places begins while students are still in high school, often through career technical education, and says the strategy has been especially useful in special education and bilingual education. San Diego Unified’s version follows that playbook closely: it uses a summer schedule, pays students for classroom work and ties the experience to elective credit and leadership training rather than unpaid volunteering.

That design solves several real school-system problems at once. A five-week, 82-hour internship is long enough for students to see the rhythms of planning, behavior management and relationship-building with younger children, but short enough to fit inside summer-learning budgets and calendars. Cluster-based placements through five hub high schools likely make supervision, transportation and principal matching easier. And because the district defines interns as assistant teachers delivering a specific set of lessons, the model can add capacity without pretending that teenagers are substitutes for credentialed staff. Districts do not have to copy San Diego Unified’s FranklinCovey partnership to learn from this; the transferable idea is to give novices structured training and a narrow, real job.

There are trade-offs. A short summer model can spark interest, but it cannot prove that a student is ready for full-time teaching or even that the student will stay on an education pathway. It also depends on adults who can recruit students early, process youth-employment paperwork, coordinate placements and supervise instruction across sites. In other words, the program works because San Diego Unified turned a lofty staffing goal into a set of calendar, payroll, training and placement decisions. That is precisely why it is more useful to other districts than another broad promise to diversify the teacher pipeline.

What the pipeline still needs to prove

San Diego Unified is not presenting Teach Lead as a standalone fix. Its TEACH-LEAD site describes the internship as one entry point in a larger pipeline, and a district announcement from February 2025 said 26 participants had entered the district’s teacher residency program the previous fall through partnerships with San Diego State University, the University of San Diego and UC San Diego. The district’s teacher intern page likewise says university interns may be hired when vacancies cannot be filled with fully credentialed teachers. In other words, the summer internship sits at the earliest end of a ladder that runs through preparation and, in shortage situations, to paid intern teaching roles.

That broader context matters because California’s staffing picture is better than it was a few years ago, but hardly settled. In May, the Commission on Teacher Credentialing said the state issued more new teaching credentials in 2024-25 than at any point in the last decade, with about 20,100 new credentials and rising enrollment in teacher-preparation programs. But the commission also warned in its 2024-25 teacher supply report that stronger entry numbers alone will not stabilize staffing without attention to turnover and working conditions. The Learning Policy Institute similarly found persistent shortages in math, science, special education and bilingual education even as state workforce investments showed early gains. For districts, that means early recruitment programs like San Diego Unified’s are promising precisely because they are not the whole answer.

For school systems looking for a practical model, the most transferable lesson in San Diego Unified’s fifth Teach Lead summer is not the celebration event. It is the district’s willingness to publish the operational blueprint: who can apply, when the work happens, what training comes first, how placements are organized, what students earn and where the pathway is supposed to lead next. The next development worth watching is whether San Diego Unified starts reporting cohort-to-cohort outcomes from teenage interns to college teacher-prep candidates, residents and eventual hires. If that data follows, Teach Lead will look less like a good summer program and more like evidence that a district can start its teacher pipeline before students even graduate high school.
