These das, ew would debate that teachersdier widel in their eectiveness. Our schools haveamazingl powerul teachers, woeull inadequateteachers, and ever gradation in between. nd ew would dispute now that these dierences have anenormous impact on how much students learn. nthe schoolhouse, nothing matters more. lthoughschools are tring to improve proessional develop-ment and mentoring o teachers alread on the job, wide agreement has emerged that replacing ineec-tive teachers with high-potential teachers can di-rectl and immediatel improve student outcomes.This consensus has generated two major responsesrom policmakers and education reormers. First,numerous eorts are underwa to improve the pipe-line o teachers entering the proession. We areencouraging more o our talented college seniors toconsider teaching, enticing mid-career proessionalsto change jobs, and retooling the was we prepareteaching candidates or the challenges o teaching.1econd, we are becoming more serious about removing the least eective teachers rom class-rooms . purred b compelling research,2 the ederalace to the Top competition,3 and major philan-thropic initiatives, states and districts across thecountr are working to revamp teacher-evaluationsstems to refect the perormance dierences ev-erone knows are there. nd as measures improve, policmakers are beginning to consider was to usethe data, such as b dismissing or dening tenure toteachers who all short on the new ratings.et in our zeal to bring in new sources o talentand relieve schools o their lowest perormers, werisk overlooking what is perhaps the most obvious,immediate source o improved teaching eectiveness: the great teachers we already have. The top  percent o .. teachers — more than800,000 o them — alread achieve a level o resultsthat could enable all o our children to meet andexceed standards, graduating rom high school reador college and careers.5 n two was, however, we areailing as a nation to capitalize on this extraordinarresource: Our nation is squandering one o its most important resources—our best teachers — and children are paing the price. { The top  percent o .. teachers —more than 800,000 o them — alreadachieve a level o results that could enableall o our children to meet and exceedstandards. Opportunit at the Top ow merica’s est Teachers ould lose the Gaps,aise the ar, and eep Our ation Great  ran . assel and mil scue assel  2 | opportunity at the top www.opportunityculture.org   →    We lose ar too many o the best teachers : n-nuall, an estimated 8 percent o these high-fiersleave teaching, a loss o about 64,000 ver e-ective teachers every year. That’s  times morethan Teach For merica brought into teaching in009.  →    We ail to leverage their talent or students’benet : ven when great teachers sta, their im- pact generall remains small over their careers.For example, onl 600 students will benet romthe instruction o an excellent elementar schoolteacher even i she stas on the job or 0 ears.7 We lack eective sstems to enable these teachersto reach more students b helping other teachersor b educating more students directl.n this report, we show that even i we achieve ourboldest current goals or top-teacher recruitment anddismissal o low perormers, the great majorit o children will still lack access to eective instruction.Our stubborn achievement gaps will persist, andadvanced learners will continue to all short o their potential. n contrast, we also show that b coupling these goals with retaining more high-perorming teachers and extending their reach to more students,nearl all children could have great teachers ear aer ear. ducation in merica would at last achieve its promise.This outcome is well within our reach — but onli we vastl expand the opportunities or top teachersto achieve success, impact, and rewards b building an “opportunit culture” in education. Our Best Teachers: A National Treasure What Having a Great Teacher Means or Students O course having a great teacher makes a dierence,but how much o a dierence? n this section, webrief recount major research, which reveals that ournation’s stubborn achievement gaps could be closedin a mere hal-decade i lagging children gained ac-cess to toda’s top teachers.n one earl stud o teaching eectiveness, re-searchers in Tennessee ound that low-perorming stu-dents with the top 0 percent o teachers learned twoto our times as much as students with the bottom 0 percent. ince then, man other rigorous studies havereturned results showing that the best teachers consis-tentl produce sizable and signicant learning gainsar in excess o their less-eective peers.s an illustration, consider 4th-grade mathemat-ics. esearchers at the highl regarded research rmD analzed student results on six well-knownstandardized math tests. The determined howmuch the tpical student progresses between rdand 4th grade.1 We can think o this amount o  progress as “a ear’s worth o learning” or 4th grade.eparatel, researchers have compared the learning achieved b students assigned to dierent teachersor 4th-grade math in two o the nation’s largestschool districts, ew ork it and os ngeles.n both studies, students assigned to the bestteachers (those in the top  percent o all teachers,or the “top quartile”) learned ar more than thoseassigned to the worst (those in the bottom percent).11ow much more? tudents with top-quartileteachers learned nearly twice as much as thosetaught by the bottom 25 percent o teachers. tu- ven i we achieve our boldest currentgoals or top-teacher recruitment anddismissal o low perormers, the greatmajorit o children will still lackaccess to eective instruction.Good teachers do not generate the learning  progress needed or lagging students. Onlgreat teachers get the job done.
