This is a tough choice - ease of location and hope for testing to proceed, or you have to take the Neste Plunge and go all-in on OOS testing right now.
If the latter, come to a family agreement. Sign up for all testing that is realistic, wherever that may be. Allocate family spending to time off/plane tickets/travel/hotel if necessary. If she is not a strong test taker, then ask her how she will be prepared if it comes to a one-and-done. She should consider setting up her own mock SAT/ACT test days under testing conditions, as surrogates for real testing days. Then execute and do well on the actual test day. Channel the mentality and skill set of competitive ECs into academic testing. After all, state championships are a single opportunity. Someone comes away that weekend a state champion. No body of work or extenuating circumstances taken into account.
Work on CFA, Dodmerb, and civilian colleges. Has she got her 3-4 month training window for the CFA scheduled? Penciled in a testing date and confirmed her administrator? Find a sample of the Dodmerb questionaire and fill out a draft form, and address any issues now, getting ahead of the mass of C2026 candidates in the Fall. Plan your strategy to get the CFA and Dodmerb done/triggered during the summer. Then all the applications will feel more like civilian college apps. You can also begin a parent common app now and then all that tedius fill-in-the-blank will be very quick for her to move through when her actual common app opens. Find out your school's culture on college-ing. Do they assign recommenders, or will DD have to ask each one herself? Does the English department have essay reviews? If not, there is even more opportunity for DD to set up dates in late summer with her English teacher to review her essays and this also opens the dialogue for her SOEs/recommendations.
