Example Achievement Log for a Office Assistant

A year in the life of a Office Assistant's log

• Jan - achievement: Migrated the entire team's calendar system from Google Calendar to Outlook. Reconciled 18 months of recurring meetings, fixed 47 double-booked slots, and trained 12 staff on new access rules. Completed in 4 days without losing a single appointment.
• Feb - feedback: Maria (Finance Director) said, 'You caught that invoice numbering error before it hit the ledger. That's the kind of thing that saves us hours of reconciliation.' Sent via email after I flagged duplicate Lexmark copier charges.
• Feb - task: Took over reception desk cover for Jade's 3-week paternity leave. Handled all incoming calls, package routing, and visitor check-in for a 40-person office. Missed one delivery slot early on but revised the sign-in sheet to catch the pattern.
• Apr - achievement: Renegotiated our cleaning contract with Bright Facilities. Reduced monthly spend from £1,680 to £1,420 per month by moving from twice-weekly to scheduled deep-clean plus spot service. Saved £3,120 year-to-date.
• May - task: Built a new filing system for the grant proposals folder after Janet complained she couldn't find the FEC reports. Created a master index and renamed 340 PDFs to match our coding standard. Still adding late submissions as they land.
• May - feedback: James (Operations Manager) said during team standup, 'The office ran smoothly while I was away. That's because the Office Assistant was on top of everything.' Mentioned specifically the vendor schedule I'd sent him.
• Jul - achievement: Processed 127 expense reports for Q3 cycle. Caught 11 with missing receipts or category errors before submission. Average turnaround was 2.1 days from receipt to approval, against a 5-day SLA.
• Aug - task: Managed the office move logistics for September. Coordinated with movers, facilities team, and 14 staff. The IT equipment arrived late and we had to improvise desk setup for 2 days, but everyone had a workspace by the morning of day 3.
• Oct - achievement: Created a master grant deadline tracker linked to our shared calendar. Automated email reminders to Janet and the team at 30, 14, and 7 days before each submission. Flagged 6 upcoming deadlines that had been missed in old spreadsheet system.
• Nov - task: Handled year-end office inventory: IT assets, furniture, supplies. Catalogued 340 items across three floors. Found that two monitors were already decommissioned, so our asset count dropped from 89 to 87 without replacing anything.
• Dec - achievement: Year-end reconciliation of all office supply spending. Matched 18 months of petty cash receipts to QuickBooks entries. Identified £340 in unreported expenses and recovered receipt scans for every item. Books balanced on first pass.

What makes a strong entry

How this becomes your review in November

I handled a wide range of administrative infrastructure this year, with a focus on systems and vendor relationships. I migrated our entire calendar system to Outlook and resolved the backlog of scheduling conflicts that had accumulated, and I renegotiated the cleaning contract to reduce monthly spend by £260 without cutting service quality. The grant deadline tracker I built in October has already caught six deadlines that would have been missed under the old spreadsheet system, and I processed over 127 expense reports in Q3 alone while flagging errors before they reached approval. Year-end reconciliation of office spending and inventory came back balanced on the first pass.
