ABA price comparison skills can support a person in identifying what they want, comparing total and unit prices, checking quantities, fees, quality, timing, accessibility, and return terms, and choosing an option. A lower unit price may require a larger payment or unwanted quantity. The useful outcome is an informed choice that fits the person's priorities and available funds.
Define the purchase question
Name the item or service, amount needed, deadline, quality or feature requirements, access needs, delivery or travel, return terms, and available funds. Compare options that can actually meet the same purpose.
Separate price measures
Record total price, unit price, quantity, taxes or fees, discounts, recurring charges, shipping, and required extras. A sale label is not a calculation. Use the merchant's current checkout information and show assumptions.
Include nonprice priorities
The person may value fit, comfort, durability, seller, timing, repairability, privacy, accessibility, or buying a smaller quantity. Present tradeoffs without treating the least expensive option as automatically correct.
Keep support person-centered
The CASP public summary supports individualized planning. The Ethics Code addresses understandable communication, client involvement, consent and assent when applicable, confidentiality, risk, and evaluation. ASHA supports AAC access.
A practical example
Kai compares 12 markers for $4.80, or $0.40 each, with 24 for $7.20, or $0.30 each. Kai needs eight and chooses the smaller total. Both calculations are correct; the chosen option fits quantity and budget.
Questions families can use
Are the options comparable? What is the total today? Which fees or future charges apply? Does quantity fit the need? Which quality and access factors matter? Can the person explain or revise the choice?
