Career and Technical Education Is Producing More College-Bound Students, Not Fewer.

EdSource reported on May 18 that a new SRI International study found Los Angeles Unified students who completed a career and technical education pathway graduated at higher rates than their peers and were also more likely to complete a college-preparatory course sequence and enroll in college. Miya Warner, the report's lead author, said the findings puncture the long-standing assumption that CTE serves mostly students who have no plans to attend college. Ben Gertner, who directs Linked Learning at LAUSD, told EdSource the district raised its CTE pathway completion rate from about 18% to nearly 25% between 2022 and 2025, while expanding the number of Linked Learning pathways from 43 to 100.

The assumption Warner's data undercuts is a specific one: that a counselor steering a student toward welding or culinary arts is steering them away from a four-year degree. LAUSD's own numbers say the opposite is happening at scale, and the expansion from 43 to 100 pathways means the effect is not a fluke of one well-run program. For a business or CTE teacher, the practical takeaway is that your course is not competing with the college-prep track. The data says it is feeding it.

Try This — Ready to Use
Ask students in your CTE or business class to name a four-year college major or career that seems to have nothing in common with the pathway they are in. Have them spend ten minutes mapping one real connection: a skill, a credential, or a habit the pathway is already building that the unrelated field would also require. Most students will find one. That exercise is the LAUSD finding in miniature, and it costs you one class period.
Try This in Any Class — Today
Two minutes before the bell, ask students to write down the one part of today's lesson they understood the least, no names required. Collect the slips and sort them before tomorrow's class. You will spend less time guessing what didn't land and more time teaching the actual gap, instead of re-explaining the parts students already had. It works in any subject, takes two minutes, and gives you a more honest signal than a show of hands ever will.

Signal Analysis
SIGNAL 01—AI / EdTech
New York's Largest Teachers Union Just Told AI Companies Who Decides.
The Development

New York State United Teachers' 82-member board of directors passed a resolution calling for developmentally appropriate limits on screen time and AI in New York schools, NYSUT announced on May 31. The resolution bars one-to-one screen or device use, including online assessments, for pre-kindergarten through second grade except to support documented needs such as translation or special education services, and it bars student-facing AI for that same age band entirely. It bars non-educationally based AI for grades three through eight, requires that AI use in any grade be supervised and educator-led, and bans "social companion" chatbots that simulate human relationships for children under 16. NYSUT President Melinda Person framed the position directly: "Educators are not anti-technology. We are pro-child." The resolution builds on New York's existing bell-to-bell cellphone ban and follows AFT President Randi Weingarten's "devices-down, eyes-up, hands-on" framework for the AI era, which Person said NYSUT is "proud to stand behind."

Why It Matters to You

A resolution from an 82-member board is not law, and NYSUT is explicit that the fight is over who decides, educators and families or the companies selling the tools. What makes this version specific enough to act on is the grade-band detail: a flat bar on student-facing AI through second grade, a narrower "non-educationally based" standard for grades three through eight, and a supervised, educator-led requirement above that. If your district's current AI policy is vaguer than that, this resolution is the language a building or district committee will likely borrow first, because it already exists and a major union has put its name on it.

Why This Matters
The resolution draws a line at "non-educationally based" AI for grades three through eight specifically, not AI in general. That distinction, not a blanket restriction, is what will end up in district policy language.
Around the Corner
NYSUT's release notes at least a dozen states have introduced or enacted legislation limiting classroom screen time, and LAUSD has already moved to ban screens through first grade. Expect more state and district policies to copy NYSUT's grade-band structure rather than write their own from scratch.

SIGNAL 02—Curriculum & Pedagogy
Illinois Just Defined What "Understanding Math" Is Supposed to Mean.
The Development

The Illinois State Board of Education formally adopted the Illinois Comprehensive Numeracy Plan, which NPR Illinois reporter Peter Hancock described on June 11 as "first-of-its-kind" in the state. The 192-page document gives classroom teachers and district officials concrete guidance on improving math instruction, and it opens by defining the term it is built around: numeracy is "the ability for all students to confidently understand, interpret, and apply mathematical concepts across all domains of mathematics in a variety of real-world and academic contexts." A state board choosing to define that term in writing, rather than leaving it to individual districts, is itself the news.

Why It Matters to You

Every math teacher already has a working definition of what it means for a student to "get it." The Illinois plan replaces individual judgment with a single state-level standard, which means a non-math teacher, an administrator building a rubric, or a parent reading a report card now has language to ask what numeracy means at your school and expect a specific answer instead of a shrug. If your district is in Illinois, expect this definition to show up in evaluation rubrics and PD agendas within the year. If you teach elsewhere, the document is worth reading anyway, since a state board has already done the work of writing the definition down.

Why This Matters
A 192-page plan that opens with a formal definition of numeracy gives every adult in the building, not just the math department, a shared term to argue from instead of a vague sense that scores should be higher.
Around the Corner
Expect math coordinators in neighboring states to request the Illinois plan as a model, the same way state literacy plans got passed around after early state reading-law adoptions. A formal definition this specific tends to travel.

SIGNAL 03—Youth Culture & Student Behavior
Britain Is Banning Social Media for Everyone Under Sixteen. The Plan Has a Start Date.
The Development

Prime Minister Keir Starmer announced on June 15 that the United Kingdom will ban social media use for anyone under 16, calling it "a big step for our country" in a recorded video message. "Social media is making our children unhappy and unsafe, and as a parent, as much as a Prime Minister, I just can't let that go on anymore," Starmer said. The ban covers Snapchat, TikTok, YouTube, Instagram, Facebook, and X, while messaging services such as WhatsApp and Signal are excluded. Starmer said he expects Parliament to take up the legislation before Christmas, with implementation in early 2027, and the government is also considering overnight curfews and breaks in infinite scrolling for users under 18. The decision follows a public comment period that drew 116,000 responses from parents, the tech industry, and children, more than 90% of whom favored an under-16 ban.

Why It Matters to You

A UK law will not bind an American classroom, but it resets what counts as a serious policy response. NYSUT's resolution this same week asks educators and families to set the limits; Starmer's plan removes the question by setting an age gate in law. Your students will hear about both, and the comparison, a union resolution versus a national ban, is likely to come up in any parent or school-board conversation about phones and apps this fall. Knowing the UK plan has a name, a timeline, and a 90% public-support figure behind it gives you something concrete to point to if that conversation reaches your building.

Why This Matters
More than 90% of 116,000 public respondents backed an outright under-16 ban. That is not a fringe position anymore, and it is the number that will get cited if a similar proposal reaches a US statehouse.
Around the Corner
Expect US state legislators to cite the UK rollout as a working model in 2027 sessions, building on the dozen-plus states that have already introduced screen-time legislation this year. A categorical age gate, not another usage cap, is the next escalation to watch for.

The Bottom Line — Three Things for a High-Agency Professional
1 If you advise students on CTE pathways, pull your own completion-to-college-enrollment numbers before fall registration. LAUSD's data undercuts the assumption a counselor might still be making about who CTE is for.
2 Compare your school's actual AI use in grades three through eight against NYSUT's "non-educationally based" standard before your next policy conversation. That phrase, not a blanket ban, is what is about to show up in district language.
3 Read the UK plan's age-gate structure now. It is the most concrete model available if your district debates phone or social media policy when school boards take up the topic next year.
