How do FLETC’s CITP and agency follow‑on trainings compare across ATF, HSI, and Secret Service in weeks and hours?

1. The CITP baseline: what everyone does and how long it lasts

FLETC’s CITP is explicitly presented as the common foundational program that “fulfills all the basic criminal investigative training requirements” for multiple federal partner organizations, and the program description and multiple sources place its duration in the general 8–12 week range—FLETC identifies it as the core criminal investigator program (no single hour total is listed in the sources) while one agency page and other reporting describe it as roughly 12 weeks and another ICE/HSI release describes it as a 56‑day program (eight weeks), reflecting variation in public descriptions ^{[1] [2] [3]}.

2. ATF: CITP plus an ATF follow‑on of roughly three months

ATF’s public materials state that the CITP component lasts approximately 12 weeks and that ATF supplies roughly half a CITP class at FLETC, and other reporting and trainee accounts indicate ATF typically conducts an agency “follow‑on academy” after CITP that is usually about an additional three months—put another way, ATF candidates commonly complete CITP (~12 weeks) followed by an agency program that trainees and alumni report as approximately another 12 weeks ^{[2] [5]}.

3. HSI: shorter CITP phrasing, then HSISAT of about 10–13 weeks

HSI/ICE materials in the reporting state that CITP for their trainees is described as a 56‑day program (eight weeks), followed by HSI’s own HSISAT course which one ICE release lists as a 71‑day program (~10 weeks) and another HSI page describes as spanning roughly 13 weeks; HSI explicitly requires graduation from both CITP and HSISAT to become a HSI special agent, meaning total training time after hire runs from roughly 18 weeks to as much as 21–22 weeks depending on which HSI description is used ^{[3] [4]}.

4. Secret Service: CITP then a follow‑on often near the Washington, DC area, about three months

Trainee accounts and consolidated reporting note that most 1811 agencies—including the Secret Service—complete CITP at FLETC and then attend an agency follow‑on academy; Secret Service historically arranges that follow‑on training at a site near Washington, DC rather than continuing at Glynco, and trainee reporting frames the follow‑on as “usually an additional 3 months,” consistent with the three‑month follow‑on pattern for several 1811 agencies ^[5].

5. Comparing weeks and the missing hours: consistent weeks, ambiguous hours

Across ATF, HSI, and Secret Service the pattern is consistent: an interagency CITP block followed by an agency‑specific academy that typically adds roughly 8–13 weeks; concrete week totals differ by source (CITP described as 56 days in HSI materials versus ~12 weeks in ATF and other reporting, HSISAT listed variously as 71 days or 13 weeks, ATF and other agencies commonly report a three‑month follow‑on) but the combined timeline for new special agents generally falls in the 4–6 month range from start of CITP through completion of agency follow‑on ^{[1] [2] [3] [4] [5]}. None of the provided sources specify a standard number of instructional hours for CITP or the follow‑on academies, so precise hour comparisons cannot be documented from this reporting ^{[1] [2] [3]}.

6. Caveats, discrepancies, and hidden drivers

The sourcing shows inconsistency—FLETC and agency releases use days, weeks, or generalized “three months” language at different times—so apparent differences may reflect editorial shorthand, enrollment cycles, or class‑by‑class variation rather than deliberate programmatic divergence; additionally, agencies that keep follow‑on training near DC (Secret Service) versus those that continue at Glynco (HSI, ATF) may create different cadence and calendars even if nominal weeks are similar, and the lack of publicly posted hour totals suggests institutional reluctance or low prioritization of publishing minute‑by‑minute curriculum metrics ^{[5] [3] [4] [2] [1]}.

Bottom line

The operational reality from the reporting is straightforward: CITP is the shared baseline (about eight–12 weeks depending on source), and ATF, HSI, and Secret Service each add agency follow‑on academies that typically run another roughly 8–13 weeks—yielding total initial training timelines in the neighborhood of four to six months—while precise instructional-hour figures are not available in the provided sources and therefore cannot be authoritatively compared here ^{[1] [2] [3] [4] [5]}.
