This timeline tracks ERBOCES from its Colorado Digital BOCES formation layer through the current Riverstone, homeschool-enrichment, governance, and finance disputes. It is scoped to ERBOCES as an institution. Riverstone and Brad Miller appear only where they materially affect ERBOCES governance, funding, litigation, or oversight.
Included: formation, name change, membership/board events, RFP and program-growth records, audit/budget milestones, CDE oversight records, the 2024 Colorado Supreme Court limit, Riverstone correspondence, and federal litigation.
Excluded: full statewide BOCES roster history, full Riverstone facility chronology, full Brad Miller career chronology, and advocacy-network interpretation not grounded in ERBOCES-specific sources.
Date caveat: several events are source-specific snapshots rather than final current facts. Reported events are labeled as reported when the retained source is media coverage rather than a primary record.
- Event: D49 formation materials later retained in the repo reference a March 27, 2013 organizational meeting for Colorado Digital BOCES.
- Why it matters: This is the earliest retained formation-sequence marker.
- Source basis:
raw/education/erboces/governance/erboces-governance-membership-followup-2026-04-19.md.
- Event: District 49 board materials and minutes show D49 ratifying Colorado Digital BOCES constitution/bylaws.
- Why it matters: This anchors D49 as a founding governance participant in the predecessor entity.
- Source basis: D49 packet/minutes retained under
raw/board-materials/el-paso-county-district-49/2013-05-09/.
- Event: Colorado Secretary of State records show formation of
Colorado Digital Board of Cooperative Education Services, with Colorado Digital BOCES as a dba in the retained filing attachment.
- Why it matters: This is the state business-registry formation date for the ERBOCES predecessor entity.
- Source basis:
raw/education/erboces/tax-identity/erboces-colorado-sos-and-propublica-tax-identity-2026-04-19.md.
- Event: A signed Colorado Digital BOCES constitution/bylaws document is retained.
- Why it matters: It is the strongest agreement-like governance record in the current corpus, but it remains historical because it still uses the predecessor name.
- Source basis:
raw/education/erboces/governance/cd-boces-constitution-and-bylaws-2018-signed-finalsite-2026-04-19.pdf.
- Event: Colorado Secretary of State records show an amendment changing the entity name to
Education reEnvisioned BOCES.
- Why it matters: This resolves Colorado Digital BOCES and ERBOCES as name-history layers of one entity unless later evidence requires a split.
- Source basis:
raw/education/erboces/tax-identity/erboces-colorado-sos-and-propublica-tax-identity-2026-04-19.md.
- Event: ERBOCES board materials record Montezuma-Cortez admission and Lis Richard's appointment/oath as representative.
- Why it matters: This is the retained primary source for one member admission layer later affected by 2026 termination action.
- Source basis:
raw/education/erboces/governance/montezuma-cortez/.
- Event: District 49 appoints John Graham as D49's sole ERBOCES board designee.
- Why it matters: This provides a dated appointment source that helps reconcile later board-roster conflicts.
- Source basis:
raw/board-materials/el-paso-county-district-49/2022-08-11/7678.txt.
- Event: ERBOCES minutes appoint Bethany Drosendahl as an at-large board member and authorize operating agreements with several HSE providers.
- Why it matters: This marks a board-composition layer and an HSE agreement-expansion point.
- Source basis:
raw/education/erboces/governance/erboces-board-minutes-2023-06.pdf.
- Event: ERBOCES RFP letter date appears in the retained current/archived RFP source.
- Why it matters: The RFP documents an application-process model for contract schools and homeschool-enrichment proposals.
- Source basis:
raw/education/erboces/authorizing/ed-reenvisioned-rfp-call-2024-2024-wayback-20241001195516.md.
- Event: The Colorado Supreme Court issues the ERBOCES v. Colorado Springs School District 11 decision.
- Why it matters: The holding creates a specific legal boundary: section
22-5-111(2), C.R.S., bars a BOCES from locating a school in a nonmember district without that district's consent.
- Source basis:
raw/education/erboces/legal/colorado-supreme-court-case-announcements-2024-05-20.pdf and raw/education/erboces/legal/justia-copy-2024-co-29-erboces-v-d11.pdf.
- Event: FY 2024-25 audit records 7,636 sFTE, total revenue of about
$85.6M, nine contract schools, 43 homeschool-enrichment programs, and purchased instructional services at 97% of total expenditures.
- Why it matters: This is the strongest retained actual-year finance and program-scale source.
- Source basis:
raw/education/erboces/financial/erboces-fy2024-25-audit.txt.
- Event: ERBOCES board packets show multiple HSE application motions and reference CDE IDEA Indicator 11/12 compliance letters.
- Why it matters: These packets show active HSE portfolio expansion and identify missing CDE correspondence as a target.
- Source basis:
raw/education/erboces/authorizing/erboces-rfp-hse-provider-outcomes-followup-2026-04-19.md.
- Event: CDE special-education administrative-unit determination rates ERBOCES as
Meets Requirements for the AU/SPP-APR context.
- Why it matters: This is a positive but context-limited CDE oversight record; it is not a global validation of authorizing, finance, or Riverstone compliance.
- Source basis:
raw/education/erboces/cde/cde-schoolview-and-au-excerpts-2026-04-19.md.
- Event: Reporting says Brad Miller wrote about a Colorado parallel test case involving Riverstone and ADF interest.
- Why it matters: This is a reported legal-strategy cue; it should not be generalized to all ERBOCES actors without further primary records.
- Source basis:
wiki/summaries/education/education-reenvisioned-boces-media-chronology-source-cluster.md.
- Event: Reporting says Pueblo County School District 70 signed off on Riverstone operating within district boundaries.
- Why it matters: This is a district-authorizer interface that still needs direct district records.
- Source basis:
wiki/summaries/education/education-reenvisioned-boces-media-chronology-source-cluster.md.
- Event: Reporting says Riverstone opened; the federal complaint later alleges Riverstone operated as a tuition-free contract school under contract with ERBOCES.
- Why it matters: This is the start of the current Riverstone funding and legal-risk sequence.
- Source basis:
raw/education/erboces/legal/erboces-riverstone-federal-complaint-2026-02-13.md and wiki/summaries/education/education-reenvisioned-boces-media-chronology-source-cluster.md.
- Event: ERBOCES board-packet evidence says Annette Ridgway resigned as CFO, Amanda Wittman was newly contracted as CFO, Riverstone met a 25-student milestone, and a signed Riverstone contract was attached.
- Why it matters: This narrows both the finance-leadership conflict and the missing signed Riverstone contract target.
- Source basis:
raw/education/erboces/authorizing/erboces-rfp-hse-provider-outcomes-followup-2026-04-19.md.
- Event: CDE sends a letter to D49 and ERBOCES questioning Riverstone's contract-school authority, nonsectarian operation, School Finance Act eligibility, and
AUD-108 contracted-services assurances.
- Why it matters: This is the strongest retained primary correspondence for the Riverstone funding dispute.
- Source basis:
raw/education/erboces/oversight/cde-2025-10-10-letter-to-erboces-and-d49-riverstone.md.
- Event: Minutes embedded in the November 2025-May 2026 CORA board-packet package support a working count of roughly 42 HSE application approvals or agreement authorizations across meetings from October 14, 2025 through April 14, 2026.
- Why it matters: This adds a board-throughput layer between aggregate ERBOCES finance and individual provider leads. The approvals require contract, application, budget, student-count, and payment-record follow-up before they can support provider-level flow claims.
- Source basis:
wiki/summaries/education/education-reenvisioned-boces-cora-board-packet-source-cluster-2026.md.
- Event: The FY 2024-25 audit report is dated October 31, 2025.
- Why it matters: It provides a dated, audited snapshot of ERBOCES board roster, administrative officials, financial statements, and program scale.
- Source basis:
raw/education/erboces/financial/erboces-fy2024-25-audit.txt.
- Event: The January 2026 revised FY 2025-26 budget reports 9,382.5 total sFTE,
$102,930,100 in program revenue, $97,281,100 in professional-educational services, and $109,371,427 in total revenue including grants.
- Why it matters: It shows the forward-looking scale of ERBOCES' contract-services financial model.
- Source basis:
raw/education/erboces/financial/erboces-fy2025-26-revised-budget-january-2026.txt.
- Event: The federal complaint alleges ERBOCES sent a second letter to CDE asking whether Riverstone funding would be clawed back based on religious identity.
- Why it matters: The date is important to plaintiffs' litigation narrative, but the underlying ERBOCES letter is not retained.
- Source basis:
raw/education/erboces/legal/erboces-riverstone-federal-complaint-2026-02-13.md.
- Event: ERBOCES minutes preserved in the March 10 packet record Elizabeth admission, Elizabeth appointing Lis Richard as representative, Lori Thompson swearing-in, several HSE/provider agreements, executive session for legal advice on BOCES law and membership requirements, and Montezuma-Cortez termination for non-engagement.
- Why it matters: This is a critical governance transition marker. The vote tables show board composition changing inside the meeting, but the exact seat/oath/appointment mechanics still require the admission packet and related records.
- Source basis:
raw/education/erboces/governance/erboces-2026-02-10-board-minutes-extract.md and wiki/summaries/education/education-reenvisioned-boces-cora-board-packet-source-cluster-2026.md.
- Event: ERBOCES and Riverstone file a federal complaint against Colorado education officials in the U.S. District Court for the District of Colorado.
- Why it matters: The dispute moves from agency correspondence and funding uncertainty into federal litigation.
- Source basis:
raw/education/erboces/legal/erboces-riverstone-federal-complaint-2026-02-13.md.
- Event: ERBOCES March 2026 minutes later preserved in the April packet record Lis Richard elected board president, James Salazar elected treasurer, twelve HSE agreement authorizations, and a PSAS Online School multi-district online-school agreement item after State Board approval. The March packet also lists new contracts for staff roles intended to support HSE and full-time program growth.
- Why it matters: It shows portfolio expansion, board reconfiguration, and staff-capacity work moving together after Riverstone litigation began.
- Source basis:
wiki/summaries/education/education-reenvisioned-boces-cora-board-packet-source-cluster-2026.md.
- Event: ERBOCES April 2026 minutes later preserved in the May packet record nine HSE agreement authorizations, 2026-2027 board-meeting-date approval, school-calendar approval, and entry into executive session for legal matters regarding ongoing Riverstone Academy litigation. The April packet also introduces bylaws revision language referencing associate membership.
- Why it matters: This shows Riverstone litigation, HSE approvals, calendar/launch operations, and governance revision moving in parallel.
- Source basis:
wiki/summaries/education/education-reenvisioned-boces-cora-board-packet-source-cluster-2026.md and wiki/summaries/education/colorado-homeschool-enrichment-funding-and-opposition-cluster-2026.md.
- Event: ERBOCES May 2026 agenda places eight additional HSE final-review items, HSE calendars, bylaws revision, teacher-appreciation resolution, proposed budget, a 5 Acre Woods new-school presentation, Q3 HSE scorecards, and finance/operations reports before the board.
- Why it matters: The May packet is the clearest launch-operations marker in the retained sequence. It lists 48 HSE programs in the HSE calendar package, says final HSE approvals were being completed in May, says all HSE evaluative site visits were complete, and presents FY 2026-27 growth/pre-funding budget statements. Later minutes are needed before treating May agenda items as adopted actions.

- What are the contents and current status of CDE's audit, CDE responses after October 2025, and any clawback decision?
- What is the current federal docket posture beyond the complaint and limited public metadata?
