"Attained 95% student proficiency" tells me you hit a number. It doesn't tell me what you did. Did you redesign the curriculum? Tutor after school? Differentiate instruction for ELL students? The verb hides the work, and hiring principals skip bullets that hide work.

Five rewrites that actually say something

Weak: Attained 92% proficiency rate on state math assessments
Strong: Raised state math proficiency from 78% to 92% by piloting a mastery-based unit system and running Saturday tutoring sessions for 18 at-risk students
Why it works: "Raised" shows direction and effort. The rewrite names two concrete strategies and quantifies the starting point, so the principal knows you owned the delta.

Weak: Attained National Board Certification in early childhood education
Strong: Earned National Board Certification in early childhood education while teaching full-time and chairing the K-2 literacy committee
Why it works: "Earned" signals effort. Adding context (full-time teaching + committee chair) shows you balanced the certification with real responsibilities, not just checked a box.

Weak: Attained 100% parent attendance at fall conferences
Strong: Secured 100% parent attendance at fall conferences by offering evening slots, translating materials into Spanish and Haitian Creole, and calling every family twice
Why it works: "Secured" implies you had to work for it. The rewrite unpacks how—evening availability, translation, personal outreach—so the principal sees your strategy, not just the outcome.

Weak: Attained reduction in classroom behavior incidents
Strong: Cut behavior incidents by 40% (from 15/month to 9/month) by introducing a restorative-circle protocol and partnering with the school social worker for weekly check-ins
Why it works: "Cut" is sharper than "attained reduction." Real numbers (15 to 9) and named tactics (restorative circles, social-worker partnership) prove you didn't just hope for better behavior—you engineered it.

Weak: Attained high student engagement scores on district climate survey
Strong: Drove student engagement scores from 68th to 91st percentile on the district climate survey by redesigning morning routines and launching a peer-mentorship program with 24 5th-graders
Strong: "Drove" shows agency. Percentile movement + two named initiatives (morning routines, peer mentorship) give the principal a mental picture of what you actually changed.

When 'attained' is the right word

If you're describing a certification or credential and the process isn't relevant, "attained" is fine—it's neutral and doesn't oversell. Example: "Attained CPR and First Aid certification." No hiring principal cares how you got CPR certified; they just need to know you have it.

If the goal was genuinely passive—something conferred on you rather than something you built—use "attained" or "received." Example: "Attained tenure in 2022." You didn't earn tenure through one action; the district granted it after years of service.

If you're listing a language proficiency or test score without a story behind it, "attained" works as filler. But if there's experience worth naming—like studying abroad or tutoring ELL students—swap "attained" for "developed" or "built."

Verb tense consistency across roles

Your current role should be in present tense. Past roles should be in past tense. Mixing them is a tell that you didn't proofread—or that you copy-pasted bullets across roles without updating the verb.

If you're still teaching at Lincoln Elementary, write: "Raise state math proficiency by 12 points annually." If you left in 2023, write: "Raised state math proficiency by 12 points in 2022–23." Recruiters and hiring principals scan tense as a proxy for attention to detail. A resume with tense errors reads as rushed, and teachers who rush their resumes often rush their lesson plans.

This rule applies to every bullet in a role block. Don't write three bullets in past tense and one in present because you forgot to update it. If you're using a tool to auto-generate bullets, double-check tense by hand. ATS screeners don't penalize tense mixing, but human readers notice it in the first six seconds, and once they notice one error, they start hunting for more.

One edge case: if you're currently employed but describing a finite project that ended, you can use past tense for that bullet even though the role is present. Example: "Piloted a new ELA curriculum (2024–25) that raised proficiency 9 points." The role is ongoing; the pilot is done. That's fine. But the bulk of your bullets should match the role's tense.
