Program accomplishments

• DIGITAL EQUITY: THE STEM ALLIANCE'S DIGITAL PATHWAYS INITIATIVE CLOSES THE DIGITAL DIVIDE BY CONNECTING LOW- AND MODERATE-INCOME RESIDENTS ACROSS WESTCHESTER COUNTY AND NEW YORK CITY TO COMPUTERS, INTERNET ACCESS, AND TECH SKILLS TRAINING. THE STEM ALLIANCE IS A REGIONAL LEADER IN DIGITAL EQUITY AND A TRUSTED PARTNER TO STATE AND LOCAL GOVERNMENTS IN ADMINISTERING THESE PROGRAMS. THE NEED IS ACUTE: AMONG THOSE SERVED, 93% NEED A DEVICE, AND 84% OF THOSE HAVE NO COMPUTER IN THE HOME AT ALL, WHILE 71% NEED BASIC COMPUTER TRAINING AND 64% OF THOSE HAD NEVER RECEIVED ANY. THIS IS NOT A TEMPORARY OR PANDEMIC-ERA PROBLEM. IT IS A PERSISTENT STRUCTURAL BARRIER THAT LOCKS RESIDENTS OUT OF THE BASIC DIGITAL SKILLS THAT 92% OF JOBS NOW REQUIRE, MAKING FULL PARTICIPATION IN A DIGITALLY DRIVEN ECONOMY IMPOSSIBLE WITHOUT INTERVENTION. SINCE 2020, THE INITIATIVE HAS DISTRIBUTED MORE THAN 5,200 COMPUTING DEVICES, CONNECTED OVER 2,300 HOUSEHOLDS TO THE INTERNET, AND SCREENED MORE THAN 5,500 RESIDENTS FOR DIGITAL NEED.THE RESULTS ESTABLISH A CLEAR PATHWAY FROM DIGITAL ACCESS TO ECONOMIC OPPORTUNITY. AMONG 3,855 CLIENTS SURVEYED BEFORE AND AFTER COMPLETING THE PROGRAM'S 15-HOUR TECH EDUCATION COURSE, COMFORT ON CORE WORKFORCE PLATFORMS SUCH AS WORD, EXCEL, AND CALENDAR MORE THAN DOUBLED, REACHING MAJORITY CONFIDENCE ACROSS EVERY PLATFORM. SPANISH-SPEAKING PARTICIPANTS, WHO ENTERED WITH THE LEAST CONFIDENCE, MADE THE LARGEST GAINS AND NARROWED THE GAP WITH THEIR ENGLISH-SPEAKING PEERS ACROSS MOST MEASURES. THE LONGER-TERM IMPACT IS DIRECT AND LASTING: IN A FOLLOW-UP SURVEY OF 1,344 CLIENTS CONDUCTED THREE TO SIX MONTHS AFTER SERVICES, 79% OR MORE REPORTED AN INCREASED LIKELIHOOD OF USING THE INTERNET TO ACCESS HEALTHCARE AND ESSENTIAL GOODS AND SERVICES, 79% REPORTED AN INCREASED LIKELIHOOD OF PURSUING FURTHER TRAINING, AND 67% REPORTED AN INCREASED LIKELIHOOD OF OBTAINING A BETTER-PAYING JOB. IN A DIGITALLY DRIVEN ECONOMY, DIGITAL INCLUSION IS AMONG THE MOST DIRECT AND SCALABLE LEVERS AVAILABLE FOR WORKFORCE DEVELOPMENT AND INDIVIDUAL EMPOWERMENT.

• STEM EDUCATION AND EQUITY: THE STEM ALLIANCE'S STEM EDUCATION AND EQUITY PROGRAMS BRIDGE SYSTEMIC GAPS IN STEM LEARNING THROUGH HANDS-ON, STANDARDS-ALIGNED PROGRAMMING ACROSS ALL STEM DISCIPLINES. THE NEED IS URGENT: WOMEN MAKE UP ONLY 35% OF THE U.S. STEM WORKFORCE AND PEOPLE OF COLOR ONLY 10%, WHILE MORE THAN HALF OF GEN Z STUDENTS REPORT LIMITED EXPOSURE TO CAREER-FOCUSED STEM. IN THE 2024-2025 YEAR, THE STEM ALLIANCE DELIVERED MORE THAN 190 HIGH-QUALITY PROGRAMS, TOTALING OVER 1,000 PARTICIPANT HOURS, IN PARTNERSHIP WITH 50 LOCAL ORGANIZATIONS. THIS WORK SERVED MORE THAN 4,300 STUDENTS FROM PRE-K THROUGH HIGH SCHOOL, WITH 60% OF PROGRAMMING REACHING RACIALLY DIVERSE COMMUNITIES. THE IMPACT IS MEASURABLE: ACROSS STUDENT SURVEYS, PARTICIPANTS REPORTED MARKED GAINS IN STEM CURIOSITY, CONFIDENCE, AND IDENTITY AFTER AS FEW AS EIGHT HOURS OF PROGRAMMING.EQUITY IS BUILT INTO THE PROGRAM'S DESIGN. CLASSES, WORKSHOPS, AND POP-UPS ARE OFTEN ORGANIZED FOR AFFINITY GROUPS, SUCH AS ALL-GIRLS COHORTS, CREATING SAFE AND WELCOMING ENVIRONMENTS FOR UNDERSERVED STUDENTS. REDUCED AND FULLY WAIVED TUITION ENSURES THAT ECONOMIC NEED IS NEVER A BARRIER TO PARTICIPATION. THE STEM ALLIANCE ALSO EXTENDS LEARNING INTO THE COMMUNITY YEAR-ROUND THROUGH PROGRAMS INCLUDING STEM-TASTIC, A FREE PUBLIC FESTIVAL SERVING MORE THAN 1,000 ATTENDEES; STEM SAILS, A HANDS-ON MARINE SCIENCE EXPERIENCE ABOARD SCHOONERS ON THE LONG ISLAND SOUND; COMPETITIVE FIRST LEGO LEAGUE ROBOTICS TEAMS THAT ADVANCED TO THE REGIONAL FINALS AT RPI FOR THE SECOND CONSECUTIVE YEAR; TINKERING NIGHTS THAT ENGAGE CHILDREN AND PARENTS IN HANDS-ON MAKING; AND AN AMC-8 MATH CLUB PREPARING MIDDLE SCHOOLERS FOR NATIONAL COMPETITION. TOGETHER, THESE PROGRAMS MEET EVERY CHILD WHERE THEY ARE, OFFERING BOTH INTENSIVE STEM EXPERIENCES AND LIGHTER-TOUCH INTRODUCTORY SO THAT PARTICIPATION IS OPEN TO ALL, FROM THE ALREADY ENTHUSED TO THE MERELY CURIOUS.
  Expenses $641,825
• CO-OP SUMMER ENRICHMENT: NOW IN ITS SIXTIETH YEAR, CO-OP SUMMER ENRICHMENT IS THE STEM ALLIANCE'S RESPONSE TO SUMMER LEARNING LOSS, THE DECLINE IN READING AND MATH SKILLS THAT DISPROPORTIONATELY AFFECTS CHILDREN FROM LOW-INCOME HOUSEHOLDS AND WIDENS THE ACHIEVEMENT GAP YEAR AFTER YEAR. AS A FIVE WEEK, FULL DAY PROGRAM, CO-OP DELIVERS HIGH-QUALITY, HANDS-ON STEM LEARNING TO MORE THAN 250 STUDENTS, BLENDING RIGOROUS ACADEMIC ENRICHMENT WITH THE RITUALS THAT MAKE SUMMER MEANINGFUL: COLOR WARS, SWIM INSTRUCTION, AND FIELD TRIPS TO STEM INSTITUTIONS SUCH AS THE INTREPID MUSEUM AND THE NEW YORK HALL OF SCIENCE. THE COMBINATION IS DELIBERATE. ENGAGING PROGRAMMING SUSTAINS THE CONSISTENT ATTENDANCE THROUGH WHICH CO-OP SLOWS SUMMER SLIDE, SUPPORTS ACADEMIC GROWTH AND KEEPS STUDENTS ON TRACK FOR THE YEAR AHEAD.THE PROGRAM'S OUTCOMES DEMONSTRATE ITS EFFECTIVENESS. IN 2025, 83% OF CAMPERS HELD OR IMPROVED THEIR READING SCORES, 91% MAINTAINED CONSISTENT ATTENDANCE, AND 100% OF EDUCATORS REPORTED THAT CO-OP HELPED STUDENTS MEET STATE AND DISTRICT BENCHMARKS. FOR THE MAJORITY OF FAMILIES SERVED, THE PROGRAM FILLS A CRITICAL GAP: 74% OF CAMPERS HAD NO SUMMER ALTERNATIVE, AND 63% REPORTED THAT CO-OP WAS THEIR CHILD'S FIRST STEM ENRICHMENT EXPERIENCE. CO-OP EXTENDS THROUGH THE MIDDLE SCHOOL YEARS THROUGH TWO ADDITIONAL PROGRAMS: MOSAIC INNOVATION CAMP AND A FIVE-WEEK RISE LEADERSHIP-IN-TRAINING PROGRAM. THE STEM ALLIANCE ALSO EMPLOYS MORE THAN 60 LOCAL TEENAGERS AND YOUNG ADULTS AS COUNSELORS AND MENTORS, ESTABLISHING A PATHWAY THAT BUILDS SKILLS AND OPPORTUNITY WELL BEYOND A SINGLE SUMMER.
  Expenses $598,264
