Executive summary

The ICE training picture at FLETC is bifurcated: Enforcement and Removal Operations (ERO) recruits are reported to flow through a compressed roughly eight‑week pipeline, while Homeland Security Investigations (HSI) special agents receive a much longer program totaling about 25–27 weeks (often described as six months) that includes a shared 12‑week Criminal Investigator Training Program (CITP) followed by agency‑specific instruction [1] [2] [3]. Available reporting describes these lengths in weeks rather than providing precise total instructional hours, so any direct hour‑by‑hour comparison against other federal basic programs at FLETC cannot be made from the supplied sources alone [1] [2].

1. A split curriculum: short ERO track versus long HSI track

ICE has intentionally separated pipelines: ERO’s basic immigration enforcement track has been characterized in reporting as an eight‑week program described by DHS leadership as “extensive training over eight weeks,” whereas HSI recruits undertake a substantially longer course—about 25–27 weeks or six months—that begins with the 12‑week CITP and continues with HSI’s specialized curriculum [1] [2] [3]. Those week counts are the clearest comparative metric available in the sources and show that, by weeks alone, HSI candidates spend roughly three times as long at FLETC as ERO recruits according to recent accounts [1] [3].

2. What the weeks mean: shared foundational training and agency‑specific follow‑ons

HSI special agents’ training model is explicitly two‑phased: a foundational CITP that is shared across many federal agencies at FLETC (about 12 weeks) followed by HSISAT (HSI Special Agent Training) which covers investigative casework, courtroom preparation, transnational crime specialties, tactical skills and sustained physical conditioning—altogether amounting to that 25–27 week total reported by ICE and other outlets [2] [3]. By contrast, reporting describes the ERO pipeline as a shortened, focused sequence that nonetheless includes firearms, driving, conflict management and de‑escalation content within its eight‑week span [1].

3. How this stacks up against “other federal basic training programs” at FLETC

FLETC’s CITP is the canonical shared basic criminal investigator course and is about 12 weeks long, which places it between the ERO and HSI endpoints: shorter than HSI’s full sequence but longer than the compressed ERO track [2]. Reporting also notes historical and older descriptions of ICE basic programs in different eras—some sources previously cited roughly 22 weeks for ICE basic training—underscoring that ICE training lengths have changed over time and that comparisons depend on which ICE track and which historical baseline one uses [4] [1].

4. Context, controversies and caveats that matter to any meaningful comparison

The shift to an eight‑week ERO track appears driven by large hiring goals and operational demands; reporting links the change to a major workforce expansion and to policy shifts that removed some prior requirements such as mandatory Spanish training for ERO recruits, which has prompted debate about field readiness and de‑escalation capacity [1]. ICE and DHS messaging emphasize “rigor and modernization” and describe training as part of a broader chain that includes field oversight and continuing instruction—an argument unions and some officials use to push back against simple week‑count comparisons [1]. FLETC also serves more than 90 federal agencies, making direct apples‑to‑apples comparisons tricky because different agencies send trainees to either the shared CITP or to entirely different basic programs with different mission emphases [3].

5. Bottom line and reporting limits

Measured in calendar weeks at FLETC, HSI’s basic training is substantially longer—roughly 25–27 weeks including a 12‑week CITP core—whereas ERO’s current basic pipeline is described as approximately eight weeks, making HSI’s program roughly three times longer in duration by that metric [1] [2] [3]. The available sources, however, do not provide a consolidated total of instructional classroom or practical training hours for each program or for other federal basic programs at FLETC, so a precise hour‑to‑hour comparison cannot be derived from the reporting provided [1] [2].
