| New student library card sign-ups | Whether students actually gain public library access. The Urban Libraries Council's Leaders Library Card Challenge reported more than 1 million new cards in its first year. | Count new student cards issued through school sign-up drives or partner communities. | Baseline before launch, end of first semester, then annually | A card in hand does not mean the student uses it. |
| Cards obtained and actively used | Whether sign-ups turn into real use. Hartford Public Library's Boundless evaluation counted 327 students who obtained and used a card. | Track which students get cards, then record later checkouts or logins on those accounts. | By the next school year | Use shows engagement, not learning gains. |
| Circulation on student accounts | Whether school-linked accounts lead to more borrowing. Baltimore County Public Library has reported increases of 500 percent or more after a school launches. | Compare student account circulation before and after launch at each school. | End of first semester, then annually | Rising checkouts can reflect new delivery routes or promotions, not the partnership alone. |
| Overall circulation of shared collections | The partnership's effect on borrowing across the system. Nashville's Limitless Libraries reported a 60 percent jump in circulation. | Compare circulation statistics before and after implementation, including titles delivered to schools. | Early check-ins, but Nashville expected at least three years of data before judging its pilot | Short-term spikes may fade, so avoid early conclusions. |
| Account reach across enrollment | Whether every enrolled student has access. Lincoln's OneCard opts in all Lincoln Public Schools students automatically. | Verify account creation against the district student roster. | Each enrollment cycle and at the annual MOU review | An account existing does not show it is being used. |
| Student participation in reading programs | The scale of student involvement. New York's statewide plan targets 2.5 million children and teens in summer reading each year by 2026. | Use an online registration tool to register students, log reading progress, and generate reports. | Annually, after the program ends | Participation counts do not measure reading growth. |
| Family event attendance and books distributed | Community reach of co-programmed events, such as Secaucus moving from 300 donated books to 1,000 for an all-district read and Family Literacy Night. | Sign-in sheets at events plus counts of books, cards, or materials handed out. | After each event, summarized each semester | Attendance does not show whether families keep reading at home. |
| Teacher feedback | Whether visits, author events, and collection loans fit classroom needs. | Short surveys or debriefs after school visits and loans. | End of first semester and annually | Responses are self-reported and reflect opinions, not student outcomes. |
| Reading outcomes, where available | Possible links between partnership activity and student achievement. | District assessment data, shared only under a data privacy agreement in the MOU. | Annual review | Hard to attribute to the partnership, and published outcome figures were not available for the programs above. |
