The honest answer is: for a while, yes
If you are searching for a BACB fieldwork tracker spreadsheet, you have already worked out the important part. You need to track your hours, nobody is going to do it for you, and a blank sheet with a date column is the fastest way to start today.
So let us be straight about it. A spreadsheet is a perfectly reasonable way to record fieldwork hours, and for your first month or two it may be better than anything else, because it is instant and you already know how to use it. Anyone who tells you a spreadsheet cannot track hours is selling something.
What a spreadsheet cannot do is the part that decides whether those hours count. This article is about where that line falls, so you can decide with your eyes open instead of finding out in month nine.
What a spreadsheet genuinely does well
Recording is the easy half, and a sheet is good at it. A row per session with the date, start and end time, the organization, and the supervisor gets you a defensible log. Add a column for each BACB hour category and you can total them at the bottom. That is real tracking, and it is free.
It is also completely portable and completely yours. Nobody can lock you out of it, change the pricing on it, or shut it down. That instinct is correct and worth protecting, which is why any tool worth using should let you export everything you put in.
Where it stops being enough
The trouble starts when recording is no longer the job. Compliance is not a total at the bottom of a column. It is a set of conditions evaluated per organization, per calendar month, against rules that differ by certification and fieldwork type.
Your supervision percentage is a monthly test, not a running average. This catches people. Under BACB fieldwork rules the supervision minimum applies to each supervisory period, so a strong March cannot rescue a thin April. A spreadsheet that shows a healthy overall percentage is answering a question nobody asked, and the number it shows you can look fine while individual months quietly fail.
Two of the ratios are cumulative, and they are different ones. Your total hours and your unrestricted proportion are measured across the full fieldwork experience, not month by month. So you are maintaining one sheet that has to answer some questions monthly and others cumulatively, and the arithmetic for each is different. The breakdown of restricted versus unrestricted hours explains why that distinction decides whether hours count.
Every workplace is scored separately. If you work at two organizations, the requirements are met at each one independently and cannot be pooled. Most homemade sheets total everything together, which is the one arrangement guaranteed to hide a problem at a single site.
The rules moved. Monthly caps, observation requirements and supervisory contacts all differ between the pre-2027 and 2027 standards. A sheet built against one rule set silently keeps applying it after your rule set changes. The pathway pages carry the sourced numbers for each combination.
The part a spreadsheet cannot do at all
Everything above is arithmetic, and arithmetic can be fixed with enough formulas and enough discipline. This next part cannot.
Your hours become official when they appear on a Monthly Fieldwork Verification Form that both you and your supervisor sign. That form is the record the BACB recognizes. A spreadsheet does not produce it, cannot be signed in any meaningful sense, and has no way to prove that the numbers on it were not edited after your supervisor agreed to them.
In practice that means the spreadsheet was never the record. It was a staging area you transcribed from, once a month, into the document that actually counted. Every transcription is a chance to introduce an error into the only artifact anyone will ever audit. Verification sign-off exists to remove that step entirely.
A reasonable rule for when to move
You do not need to switch on day one. A fair trigger is any of these becoming true: you are working at more than one organization, you have more than one supervisor, you are past your third month, or you have already had to reconstruct a month from memory.
Any one of those means the sheet is now costing you more than it saves. Two of them and you are maintaining a second job.
If you do move, you are not throwing the sheet away. Your existing months come in as verified monthly summaries, so your progress reflects your whole journey rather than restarting at zero. The guide on how to import past fieldwork hours covers exactly what transfers and what does not.
What actually changes day to day
The difference is not that logging gets faster. Logging a session takes about the same time either way. The difference is that the checking stops being your job.
You enter a session and the compliance checks run against your pathway’s actual requirements, per organization, for that calendar month, as you go. When something falls short you find out in week two while you can still do something about it, rather than at the end of the month when the only available option is to explain it.
And when the month closes, the verification form is generated from the hours you already logged and sent to your supervisor to sign. No transcription, no second copy, no version of the truth that lives only in a file on your laptop.
If you want to try it
Registration is free, there is no card, and you can log one real session in about a minute to see whether the checks tell you anything your sheet was not telling you. That is a cheap experiment, and it is a lot cheaper than discovering a gap in month nine.
Keep the spreadsheet. Run both for a month if it makes you comfortable. The point is not that spreadsheets are bad. The point is that the hours are your career, and the arithmetic that decides whether they count deserves something that checks it for you.
