A token economy is a reinforcement system in which earned tokens, points, marks, or board pieces are exchanged for backup reinforcers. Tested under C.11 of the BACB RBT Test Content Outline (3rd ed.), the RBT-level skill is following the written earning and exchange rules.
How C.11 Appears In Study Scenarios#
The RBT Test Content Outline (3rd ed.) states C.11 as: "Implement token economies." That wording points to carrying out an existing system, not designing a reward program independently.
C.11 study scenarios can ask learners to:
- Identify whether tokens follow the target response.
- Track the count needed before exchange.
- Distinguish the token from the backup reinforcer.
- Notice when exchange rules, menus, or response-cost steps change outside the written procedure.
- Separate token systems from shaping, chaining, preference assessment, or simple praise delivery.
The parent rbt behavior acquisition study guide shows where token systems sit among reinforcement, conditioned reinforcers, teaching formats, prompts, maintenance, and shaping. The rbt practice test behavior acquisition mixes C.11 with other Domain C tasks so the topic does not cue every answer.
What A Token Economy Includes#
The table below separates the parts of a token economy that original study scenarios can test.
| Part of the system | Plain-language meaning | Example cue in a scenario | RBT-level focus |
|---|---|---|---|
| Target response | The behavior that earns tokens. | Independent item, greeting, cleanup step, or request. | Deliver tokens only when the response meets the written criterion. |
| Token | The earned symbol, object, point, or mark. | Clip, sticker, check mark, bead, point, or board piece. | Treat the token as the exchange item, not the backup reinforcer. |
| Exchange rule | The number or condition for trading tokens. | Five checks trade for one activity choice. | Preserve the count, timing, and exchange opportunity. |
| Backup reinforcer | The item, activity, or privilege available after exchange. | Drawing time, song choice, building set, or break. | Offer allowed options and report loss of value. |
| Response cost | A programmed token loss after a defined response, when included. | One point is removed for a listed rule violation. | Use only if the plan includes it and the RBT is trained. |
| Schedule change | A planned change to required responses or tokens. | The system moves from one token per response to one token per set. | Follow the current rule and ask for direction if unclear. |
Tokens are closely related to conditioned reinforcers because their value is learned through exchange. When a scenario asks how a token became valuable, the tested idea may be conditioned reinforcement rather than the exchange system.
Implementation Pattern#
The steps below describe the C.11 pattern for exam study.
- Read the written rule for the target response, token type, earning schedule, exchange count, backup menu, and data code.
- Present the teaching or work opportunity as written.
- Deliver the token after the defined response occurs, using the current schedule.
- Avoid giving tokens before the response or outside the criterion.
- Allow exchange under the listed count, timing, and menu rule.
- Record tokens earned, exchanged, or removed if required.
- Report unclear rules, lost token value, unavailable backup items, or unexpected patterns instead of redesigning the system.
A token system can support many acquisition procedures. The C.11 study signal is the earning-and-exchange rule, not the skill being taught with that system.
Examples And Non-Examples#
The examples below show when C.11 is the main study signal and when another task is more direct.
| Scenario | Example? | Why |
|---|---|---|
| A learner earns a bead after each independent response and trades six beads for an activity. | Yes | The scenario includes earned tokens, a count, and a backup reinforcer. |
| A learner completes a cleanup chain and receives brief praise after the final step. | Not mainly C.11 | The scenario focuses on an ordered routine and direct praise, not earned exchange items. |
| A board shows four empty spaces, and each correct trial adds one icon toward a later choice. | Yes | The board is a visible token display with an exchange condition. |
| A learner chooses between blocks, music, and drawing before teaching begins. | Not mainly C.11 | The scenario describes preference assessment or choice making, not token earning. |
| A point is removed after a listed rule violation because the written procedure includes response cost. | C.11 if programmed | Token removal can belong to the system, but only when the plan specifies the rule. |
Token systems and shaping can appear together. Use shaping ABA when the scenario turns on changing which form of one response earns reinforcement.
Worked Token-Board Scenario#
This scenario shows how a token-board item can test C.11.
| Teaching moment | Written rule | What happens | Study interpretation |
|---|---|---|---|
| Start of work | One icon follows each completed matching set. | The board starts empty. | No token has been earned yet. |
| Correct response | The learner completes one set independently. | The RBT adds one icon. | The token is contingent on the target response. |
| Board progress | Five icons are needed for exchange. | The board now shows three icons. | The exchange condition has not been met yet. |
| Exchange | Five icons trade for one listed activity. | The learner selects drawing from the menu. | Drawing is the backup reinforcer, not the token. |
| Implementation error | An icon is added before work starts to "motivate" the learner. | No target response occurred first. | The token is not contingent under the written earning rule. |
The study point is the relation among response, token, count, exchange, and backup reinforcer.
Sibling Concepts#
The table below separates token economies from nearby Behavior Acquisition topics.
| Concept | How it differs from C.11 | When it applies |
|---|---|---|
| Conditioned reinforcer | Explains how a learned reinforcer gets value. | The stem asks why a point, card, or signal now supports responding. |
| Positive reinforcement | Focuses on adding a consequence after behavior. | The stem lacks saved tokens or later exchange. |
| Shaping | Changes the response criterion across closer approximations. | The stem focuses on which form of one response currently earns reinforcement. |
| Chaining | Links separate steps into an ordered routine. | The stem lists steps such as gather, open, wash, dry, or put away. |
| Preference assessment | Identifies possible reinforcers before or during programming. | The stem asks how options are sampled, not how tokens are exchanged. |
Common Mistakes#
The mistakes below are common C.11 errors in original study scenarios.
- Calling any sticker, point, or praise statement a token system without an exchange rule.
- Treating the backup item as the token.
- Delivering tokens before the target response.
- Changing the required token count without direction.
- Adding response cost when the written procedure does not include token loss.

These original items test C.11 implementation without using recalled exam content.
1. During reading practice, Lena earns one check mark after each independent answer. Five checks trade for a book choice. Which part is the backup reinforcer?
A Correct. The book choice is received after exchange and functions as the backup reinforcer.
B The check mark is the earned token that leads to the later exchange.
C The reading answer is the target response that earns a token.
D The board space displays progress but is not the exchange outcome.
2. A teaching rule says one clip follows each completed sorting set. An RBT places two clips on the strip before the first set starts. What is the implementation issue?
A Keeping the count visible can fit the display rule and is not the issue described.
B Correct. The clips were added before the target response occurred.
C Keeping the menu the same would preserve, not violate, the exchange rule.
D The stem does not state that the sorting sets were too short or incomplete.
3. A classroom card says six marks trade for one listed activity. Mina has four marks and asks to trade now. What best fits the written rule?
A Starting a new menu changes the system rather than applying the listed exchange count.
B Trading early changes the exchange rule from the one described in the scenario.
C Correct. The listed exchange condition is six marks, and four have been earned.
D Removing a mark would be response cost, which is not described in the rule.
4. A plan lists stickers that trade for drawing, puzzles, or a short walk. The walk option is unavailable today. What should the RBT notice?
A The number of earned stickers is not the changed feature in this scenario.
B Response form would matter for shaping, not for the missing exchange option.
C Prompt level would matter for prompting or fading, not for the unavailable activity.
D Correct. One listed backup option is unavailable, so the exchange menu changed.
5. During math practice, Omar earns a point after each independent problem. Later he trades points for a puzzle. What feature identifies the system?
A Correct. Points are earned after responses and later exchanged for a backup item.
B Longer response timing would point to duration or latency, not token exchange.
C Varied stimulus sets would point to generalization procedures.
D Fixed routine order would point to chaining a sequence of steps.
FAQ
What is a token economy in ABA?
A token economy in ABA is a system where responses earn tokens that can later be exchanged for backup reinforcers. Tokens may be marks, points, clips, cards, or board pieces when the system gives them exchange value.
What is a token board?
A token board is a visual display that shows earned tokens and progress toward exchange. The board is not the whole system; the target response, delivery rule, exchange count, and backup menu also matter.
Why are token systems considered flexible?
Token systems are flexible because the same earned token can be exchanged for different backup reinforcers when the menu allows that range. Flexibility does not mean the RBT can change the menu or exchange count independently.
Is a sticker chart always a token economy?
No. A sticker chart is a token economy only when the stickers are earned under a rule and can be exchanged for backup reinforcers or access named by the system.
Does the BACB publish exact token-economy exam questions?
No. The BACB publishes the RBT Test Content Outline (3rd ed.), not exact exam wording. C.11 states that candidates should implement token economies.
