This article explains common mappings for step 4 in 5-step, 7-step and 9-step diagrams and offers a practical checklist to identify the stage on any authoritative flowchart. It also points readers to primary chamber sources for verification.
What people mean when they ask “What is step 4?”
how a bill becomes a law flowchart
When someone asks “What is step 4?” they are usually looking at a numbered explanatory diagram and want to know which procedural stage that number represents. Numbered flowcharts are shorthand, not fixed law. A single number can mean different things depending on how the author grouped stages and which chamber the chart follows, so step 4 is best read as a position in a diagram rather than a universal procedure.
Official guides list a consistent set of core stages that most flowcharts compress or expand: introduction, committee consideration including markup, floor consideration, reconciliation or conference, and presidential action. For readers who want to map a numbered step to a specific action, those core stages are the baseline for comparison according to the congressional explanatory guide Congress.gov legislative process guide.
Different educational diagrams use different totals. A compact five-step flow often combines several committee and floor stages and places reconciliation near the end. Longer seven- or nine-step diagrams separate subcommittee review, reporting, and engrossment, which moves the numerical position of stages like markup or conference. Because the number depends on the model, it is not safe to assume a single correct mapping without checking the chart’s legend or source.
Those expanded frameworks clarify more of the internal steps that bills typically pass through, but they also mean readers must match the diagram’s labels to the chart’s numbering before they translate a number into an action. An expanded diagram is useful for students or practitioners who need procedural detail, while compact diagrams prioritize an overview that highlights final passage and presidential action.
Common flowchart frameworks and where Step 4 usually lands
5-step diagrams: Step 4 as reconciliation
Many civic one-page summaries and simplified classroom charts present a five-step layout. In that model the final steps compress intra-chamber work and show an interchamber harmonization phase before presidential action. In those diagrams Step 4 commonly represents conference or reconciliation, the stage where House and Senate texts are combined and settled prior to enrollment and a presidential signature, as shown in standard Senate and congressional explainers U.S. Senate overview.
7-step and 9-step diagrams: Step 4 as committee or floor action
Longer diagrams that list subcommittee hearings, markup, reporting to the full committee, and final committee votes tend to place committee-level action earlier in the sequence. In many seven- and nine-step models, the fourth numbered step is often committee markup or formal reporting to the floor rather than reconciliation. This pattern appears in chamber-specific guidance that separates subcommittee work from full committee reporting House Clerk legislative process and the House overview House overview.
Those expanded frameworks clarify more of the internal steps that bills typically pass through, but they also mean readers must match the diagram’s labels to the chart’s numbering before they translate a number into an action. An expanded diagram is useful for students or practitioners who need procedural detail, while compact diagrams prioritize an overview that highlights final passage and presidential action.
When Step 4 represents floor consideration
What floor consideration includes in each chamber
When a flowchart uses Step 4 to mean floor consideration, it is referring to the stage where the full chamber debates the bill, considers amendments, and votes on final passage. That combination of debate, amendment activity, and a recorded vote is what most chamber guides describe as floor consideration and final chamber action House Clerk legislative process.
Floor consideration can include negotiated amendment processes and rule-based time limits in the House, and it can include extended amendment trees, holds, or unanimous consent agreements in the Senate. Those procedural differences affect what actually happens during a numbered step that represents the floor.
Stay informed about procedural guides and campaign updates
Consult the chamber guide cited in the paragraphs above to see how the chart defines floor consideration and any special rules that affect timing.
Because the House and Senate operate under different rules, a chart that follows only one chamber will place floor consideration at different points relative to committee steps. Charts that combine both chambers into one linear sequence may show a single shared floor step that abstracts away chamber-specific rules, so confirm which chamber’s practice the diagram is describing.
When Step 4 means reconciliation or conference committee
What reconciliation or conference committees do
When Step 4 denotes reconciliation, the diagram is marking the phase where representatives from both chambers reconcile competing versions of a bill. A formal conference committee or a managers’ agreement aims to produce a single text that both chambers will approve before the bill is enrolled and sent to the president. For a concise explanation of the formal conference process and its purpose, see the CRS explainer on conference committees CRS report on conference committees.
Step 4 varies by the flowchart model; in compact 5-step charts it is often reconciliation, while in longer 7- or 9-step charts it is frequently committee markup or floor consideration. Confirm by checking the chart's labels and the chamber guide.
Not every disagreement between chambers leads to a formal conference committee. Alternate practices include exchange of amendments, managers’ agreements, or sending amended text back and forth until both chambers agree. Flowcharts that show reconciliation as a distinct step emphasize formal conferences, while others fold the harmonization process into a final passage or enrollment step and do not show an explicit conference stage.
How chamber differences change the numbering (decision criteria)
House-specific scheduling and reporting
The House often highlights the role of its Rules Committee, which controls the terms of floor debate, amendment scope, and scheduling. When a chart follows House procedure closely, Step 4 can appear after committee reporting and before Rules Committee action or floor debate, depending on whether the chart separates scheduling from consideration. The House Clerk’s materials describe how committee reporting and rules scheduling shape the timeline for floor consideration House Clerk legislative process.
Senate amendment practice and holds
The Senate places emphasis on unanimous consent agreements, amendment trees, holds, and the possibility of extended debate or filibuster in the absence of agreement. A flowchart focused on Senate practice might position a numbered step to reflect complex amendment exchange and cloture votes, which alters where Step 4 falls in the sequence compared with a House-focused chart. The Senate overview explains the amendment and consent customs that can change timing U.S. Senate overview.
To decide which mapping applies to your chart, check whether the chart labels the chamber or shows separate parallel flows. If the chart is ambiguous, consult the chamber guide tied to the chart’s source or use the official Congress.gov description as a neutral baseline.
A practical checklist: how to identify Step 4 on any flowchart

Help readers verify what Step 4 represents on a given flowchart
Scan labels first
Start by scanning the chart for explicit labels such as markup, report, floor consideration, conference committee, engrossment, or enrollment. Those words are direct clues to what a numbered step represents. If the chart lists subcommittee, reporting, and markup separately, Step 4 is likely a committee-level action rather than reconciliation.
Next, confirm which chamber the chart follows. A chart labeled for the House will reflect Rules Committee scheduling; a Senate chart will reflect amendment exchanges and unanimous consent practices. If the chart combines both chambers without separate lanes, treat the numbered steps as an abstraction and use the chart legend or accompanying text to identify the intended meaning.
Also check for omitted stages. Common omissions include engrossment or enrollment as separate steps and informal reconciliation as an unlabelled exchange. If those stages are missing, the chart may compress reconciliation into a final passage step, which means Step 4 could occupy a different role than in a diagram that lists every stage.
Examples and scenarios: mapping Step 4 in 5-step, 7-step and 9-step charts
Sample mapping for a 5-step chart
Typical 5-step charts often present: 1) Introduction, 2) Committee, 3) Floor, 4) Conference or reconciliation, 5) Presidential action. In that pattern Step 4 is the point at which the two chambers harmonize differences before final approval and enrollment. This compact mapping is common in civic one-page summaries and aligns with concise Senate and congressional summaries U.S. Senate overview. (see Introduction and Referral of Bills on Congress.gov)
Sample mapping for a 7-step chart
A common seven-step mapping might show: 1) Introduction, 2) Subcommittee review, 3) Committee markup and report, 4) Floor consideration, 5) Other chamber consideration, 6) Conference or reconciliation if needed, 7) Presidential action. Under this layout Step 4 most often corresponds to floor consideration in the originating chamber because the chart separates subcommittee and committee reporting stages, a pattern seen in detailed House materials House Clerk legislative process.
Sample mapping for a 9-step chart
Nine-step charts expand further to show distinct reporting, engrossment or enrollment, and return amendments. An illustrative nine-step sequence could be: 1) Introduction, 2) Referral to subcommittee, 3) Subcommittee hearing, 4) Committee markup, 5) Committee report to floor, 6) Floor consideration, 7) Second chamber committee and floor steps, 8) Conference committee if needed, 9) Enrollment and presidential action. In that model Step 4 is often committee markup because the chart separates hearing and reporting steps earlier in the sequence. The Library of Congress and explanatory analysts describe these expanded mappings for readers who want finer procedural detail Congress.gov legislative process guide.
Remember that hybrid or educational charts sometimes mix House and Senate steps into a single linear flow to simplify presentation. Those hybrid charts can shift where Step 4 sits relative to a chamber-specific diagram, so treat examples as common patterns rather than universal rules.
Common mistakes and things to avoid when reading flowcharts
A frequent error is assuming that Step 4 always means reconciliation. That mistake happens when a reader applies a compact five-step expectation to an expanded chart that lists committee and floor stages separately. To avoid this error, match labels on the chart to procedural definitions rather than relying solely on numbering. Library of Congress and educational glossaries emphasize reading labels and legends for precise mapping Library of Congress legislative flowchart guide. See also How a Bill Becomes a Law – UT Austin.
Another common misread is ignoring subcommittee steps. If a chart lists subcommittee review, then committee markup, then reporting, the presence of those separate items usually pushes reconciliation later in the sequence. If you see engrossment or enrollment omitted, the chart may compress final technical steps into a single end-stage, which affects how you interpret Step 4.
Finally, avoid assuming chamber parity. The House and Senate use different procedures that can change both timing and content of steps. When in doubt, check the chart’s source and consult the chamber’s official guidance to confirm whether a step corresponds to committee action, floor consideration, or reconciliation.
Conclusion and recommended primary sources
Main takeaway: Step 4 is a label, not a fixed rule. Which action it denotes depends on how the flowchart defines and orders procedural stages. Use chart labels and the practical checklist above to map a numbered position to the corresponding procedure.
For authoritative verification, consult primary chamber resources and the central congressional guide. Useful starting points are the Congress.gov explanation of the legislative process, the House Clerk materials for chamber-specific detail, and the Senate overview for Senate practice. For context on reconciliation and conference committees, the Congressional Research Service is a concise resource Congress.gov legislative process guide.
No. Step 4 depends on the flowchart's structure. In compact 5-step charts it often signals reconciliation, but in longer charts it can indicate committee markup or floor consideration.
Look for chamber labels, mentions of the House Rules Committee or Senate unanimous consent, and whether subcommittee steps are shown; those clues indicate which chamber's practice the chart follows.
Primary sources include the Congress.gov legislative process guide, the House Clerk's process materials, and the U.S. Senate overview.
